Accuracy of the tz database

----- Scope of the tz database -----
The tz database attempts to record the history and predicted future of
all computer-based clocks that track civil time. To represent this
data, the world is partitioned into regions whose clocks all agree
about time stamps that occur after the somewhat-arbitrary cutoff point
of the POSIX Epoch (1970-01-01 00:00:00 UTC). For each such region,
the database records all known clock transitions, and labels the region
with a notable location. Although 1970 is a somewhat-arbitrary
cutoff, there are significant challenges to moving the cutoff earlier
even by a decade or two, due to the wide variety of local practices
before computer timekeeping became prevalent.
Clock transitions before 1970 are recorded for each such location,
because most systems support time stamps before 1970 and could
misbehave if data entries were omitted for pre-1970 transitions.
However, the database is not designed for and does not suffice for
applications requiring accurate handling of all past times everywhere,
as it would take far too much effort and guesswork to record all
details of pre-1970 civil timekeeping.
As described below, reference source code for using the tz database is
also available. The tz code is upwards compatible with POSIX, an
international standard for UNIX-like systems. As of this writing, the
current edition of POSIX is:
The Open Group Base Specifications Issue 7
IEEE Std 1003.1, 2013 Edition
<http://pubs.opengroup.org/onlinepubs/9699919799/>
----- Names of time zone rules -----
Each of the database's time zone rules has a unique name.
Inexperienced users are not expected to select these names unaided.
Distributors should provide documentation and/or a simple selection
interface that explains the names; for one example, see the 'tzselect'
program in the tz code. The Unicode Common Locale Data Repository
<http://cldr.unicode.org/> contains data that may be useful for other
selection interfaces.
The time zone rule naming conventions attempt to strike a balance
among the following goals:
* Uniquely identify every region where clocks have agreed since 1970.
This is essential for the intended use: static clocks keeping local
civil time.
* Indicate to experts where that region is.
* Be robust in the presence of political changes. For example, names
of countries are ordinarily not used, to avoid incompatibilities
when countries change their name (e.g. Zaire->Congo) or when
locations change countries (e.g. Hong Kong from UK colony to
China).
* Be portable to a wide variety of implementations.
* Use a consistent naming conventions over the entire world.
Names normally have the form AREA/LOCATION, where AREA is the name
of a continent or ocean, and LOCATION is the name of a specific
location within that region. North and South America share the same
area, 'America'. Typical names are 'Africa/Cairo', 'America/New_York',
and 'Pacific/Honolulu'.
Here are the general rules used for choosing location names,
in decreasing order of importance:
Use only valid POSIX file name components (i.e., the parts of
names other than '/'). Do not use the file name
components '.' and '..'. Within a file name component,
use only ASCII letters, '.', '-' and '_'. Do not use
digits, as that might create an ambiguity with POSIX
TZ strings. A file name component must not exceed 14
characters or start with '-'. E.g., prefer 'Brunei'
to 'Bandar_Seri_Begawan'. Exceptions: see the discussion
of legacy names below.
A name must not be empty, or contain '//', or start or end with '/'.
Do not use names that differ only in case. Although the reference
implementation is case-sensitive, some other implementations
are not, and they would mishandle names differing only in case.
If one name A is an initial prefix of another name AB (ignoring case),
then B must not start with '/', as a regular file cannot have
the same name as a directory in POSIX. For example,
'America/New_York' precludes 'America/New_York/Bronx'.
Uninhabited regions like the North Pole and Bouvet Island
do not need locations, since local time is not defined there.
There should typically be at least one name for each ISO 3166-1
officially assigned two-letter code for an inhabited country
or territory.
If all the clocks in a region have agreed since 1970,
don't bother to include more than one location
even if subregions' clocks disagreed before 1970.
Otherwise these tables would become annoyingly large.
If a name is ambiguous, use a less ambiguous alternative;
e.g. many cities are named San José and Georgetown, so
prefer 'Costa_Rica' to 'San_Jose' and 'Guyana' to 'Georgetown'.
Keep locations compact. Use cities or small islands, not countries
or regions, so that any future time zone changes do not split
locations into different time zones. E.g. prefer 'Paris'
to 'France', since France has had multiple time zones.
Use mainstream English spelling, e.g. prefer 'Rome' to 'Roma', and
prefer 'Athens' to the Greek 'Αθήνα' or the Romanized 'Athína'.
The POSIX file name restrictions encourage this rule.
Use the most populous among locations in a zone,
e.g. prefer 'Shanghai' to 'Beijing'. Among locations with
similar populations, pick the best-known location,
e.g. prefer 'Rome' to 'Milan'.
Use the singular form, e.g. prefer 'Canary' to 'Canaries'.
Omit common suffixes like '_Islands' and '_City', unless that
would lead to ambiguity. E.g. prefer 'Cayman' to
'Cayman_Islands' and 'Guatemala' to 'Guatemala_City',
but prefer 'Mexico_City' to 'Mexico' because the country
of Mexico has several time zones.
Use '_' to represent a space.
Omit '.' from abbreviations in names, e.g. prefer 'St_Helena'
to 'St._Helena'.
Do not change established names if they only marginally
violate the above rules. For example, don't change
the existing name 'Rome' to 'Milan' merely because
Milan's population has grown to be somewhat greater
than Rome's.
If a name is changed, put its old spelling in the 'backward' file.
This means old spellings will continue to work.
The file 'zone1970.tab' lists geographical locations used to name time
zone rules. It is intended to be an exhaustive list of names for
geographic regions as described above; this is a subset of the names
in the data. Although a 'zone1970.tab' location's longitude
corresponds to its LMT offset with one hour for every 15 degrees east
longitude, this relationship is not exact.
Older versions of this package used a different naming scheme,
and these older names are still supported.
See the file 'backward' for most of these older names
(e.g., 'US/Eastern' instead of 'America/New_York').
The other old-fashioned names still supported are
'WET', 'CET', 'MET', and 'EET' (see the file 'europe').
Older versions of this package defined legacy names that are
incompatible with the first rule of location names, but which are
still supported. These legacy names are mostly defined in the file
'etcetera'. Also, the file 'backward' defines the legacy names
'GMT0', 'GMT-0', 'GMT+0' and 'Canada/East-Saskatchewan', and the file
'northamerica' defines the legacy names 'EST5EDT', 'CST6CDT',
'MST7MDT', and 'PST8PDT'.
Excluding 'backward' should not affect the other data. If
'backward' is excluded, excluding 'etcetera' should not affect the
remaining data.
----- Time zone abbreviations -----
When this package is installed, it generates time zone abbreviations
like 'EST' to be compatible with human tradition and POSIX.
Here are the general rules used for choosing time zone abbreviations,
in decreasing order of importance:
Use abbreviations that consist of three or more ASCII letters.
Previous editions of this database also used characters like
' ' and '?', but these characters have a special meaning to
the shell and cause commands like
set `date`
to have unexpected effects.
Previous editions of this rule required upper-case letters,
but the Congressman who introduced Chamorro Standard Time
preferred "ChST", so the rule has been relaxed.
This rule guarantees that all abbreviations could have
been specified by a POSIX TZ string. POSIX
requires at least three characters for an
abbreviation. POSIX through 2000 says that an abbreviation
cannot start with ':', and cannot contain ',', '-',
'+', NUL, or a digit. POSIX from 2001 on changes this
rule to say that an abbreviation can contain only '-', '+',
and alphanumeric characters from the portable character set
in the current locale. To be portable to both sets of
rules, an abbreviation must therefore use only ASCII
letters.
Use abbreviations that are in common use among English-speakers,
e.g. 'EST' for Eastern Standard Time in North America.
We assume that applications translate them to other languages
as part of the normal localization process; for example,
a French application might translate 'EST' to 'HNE'.
For zones whose times are taken from a city's longitude, use the
traditional xMT notation, e.g. 'PMT' for Paris Mean Time.
The only name like this in current use is 'GMT'.
Use 'LMT' for local mean time of locations before the introduction
of standard time; see "Scope of the tz database".
If there is no common English abbreviation, use numeric offsets like
-05 and +0830 that are generated by zic's %z notation.
[The remaining guidelines predate the introduction of %z.
They are problematic as they mean tz data entries invent
notation rather than record it. These guidelines are now
deprecated and the plan is to gradually move to %z for
inhabited locations and to "-00" for uninhabited locations.]
If there is no common English abbreviation, abbreviate the English
translation of the usual phrase used by native speakers.
If this is not available or is a phrase mentioning the country
(e.g. "Cape Verde Time"), then:
When a country is identified with a single or principal zone,
append 'T' to the country's ISO code, e.g. 'CVT' for
Cape Verde Time. For summer time append 'ST';
for double summer time append 'DST'; etc.
Otherwise, take the first three letters of an English place
name identifying each zone and append 'T', 'ST', etc.
as before; e.g. 'VLAST' for VLAdivostok Summer Time.
Use UT (with time zone abbreviation 'zzz') for locations while
uninhabited. The 'zzz' mnemonic is that these locations are,
in some sense, asleep.
Application writers should note that these abbreviations are ambiguous
in practice: e.g. 'CST' has a different meaning in China than
it does in the United States. In new applications, it's often better
to use numeric UT offsets like '-0600' instead of time zone
abbreviations like 'CST'; this avoids the ambiguity.
----- Accuracy of the tz database -----
The tz database is not authoritative, and it surely has errors.
Corrections are welcome and encouraged; see the file CONTRIBUTING.
Users requiring authoritative data should consult national standards
bodies and the references cited in the database's comments.
Errors in the tz database arise from many sources:
* The tz database predicts future time stamps, and current predictions
will be incorrect after future governments change the rules.
For example, if today someone schedules a meeting for 13:00 next
October 1, Casablanca time, and tomorrow Morocco changes its
daylight saving rules, software can mess up after the rule change
if it blithely relies on conversions made before the change.
* The pre-1970 entries in this database cover only a tiny sliver of how
clocks actually behaved; the vast majority of the necessary
information was lost or never recorded. Thousands more zones would
be needed if the tz database's scope were extended to cover even
just the known or guessed history of standard time; for example,
the current single entry for France would need to split into dozens
of entries, perhaps hundreds.
* Most of the pre-1970 data entries come from unreliable sources, often
astrology books that lack citations and whose compilers evidently
invented entries when the true facts were unknown, without
reporting which entries were known and which were invented.
These books often contradict each other or give implausible entries,
and on the rare occasions when they are checked they are
typically found to be incorrect.
* For the UK the tz database relies on years of first-class work done by
Joseph Myers and others; see <http://www.polyomino.org.uk/british-time/>.
Other countries are not done nearly as well.
* Sometimes, different people in the same city would maintain clocks
that differed significantly. Railway time was used by railroad
companies (which did not always agree with each other),
church-clock time was used for birth certificates, etc.
Often this was merely common practice, but sometimes it was set by law.
For example, from 1891 to 1911 the UT offset in France was legally
0:09:21 outside train stations and 0:04:21 inside.
* Although a named location in the tz database stands for the
containing region, its pre-1970 data entries are often accurate for
only a small subset of that region. For example, Europe/London
stands for the United Kingdom, but its pre-1847 times are valid
only for locations that have London's exact meridian, and its 1847
transition to GMT is known to be valid only for the L&NW and the
Caledonian railways.
* The tz database does not record the earliest time for which a zone's
data entries are thereafter valid for every location in the region.
For example, Europe/London is valid for all locations in its
region after GMT was made the standard time, but the date of
standardization (1880-08-02) is not in the tz database, other than
in commentary. For many zones the earliest time of validity is
unknown.
* The tz database does not record a region's boundaries, and in many
cases the boundaries are not known. For example, the zone
America/Kentucky/Louisville represents a region around the city of
Louisville, the boundaries of which are unclear.
* Changes that are modeled as instantaneous transitions in the tz
database were often spread out over hours, days, or even decades.
* Even if the time is specified by law, locations sometimes
deliberately flout the law.
* Early timekeeping practices, even assuming perfect clocks, were
often not specified to the accuracy that the tz database requires.
* Sometimes historical timekeeping was specified more precisely
than what the tz database can handle. For example, from 1909 to
1937 Netherlands clocks were legally UT+00:19:32.13, but the tz
database cannot represent the fractional second.
* Even when all the timestamp transitions recorded by the tz database
are correct, the tz rules that generate them may not faithfully
reflect the historical rules. For example, from 1922 until World
War II the UK moved clocks forward the day following the third
Saturday in April unless that was Easter, in which case it moved
clocks forward the previous Sunday. Because the tz database has no
way to specify Easter, these exceptional years are entered as
separate tz Rule lines, even though the legal rules did not change.
* The tz database models pre-standard time using the proleptic Gregorian
calendar and local mean time (LMT), but many people used other
calendars and other timescales. For example, the Roman Empire used
the Julian calendar, and had 12 varying-length daytime hours with a
non-hour-based system at night.
* Early clocks were less reliable, and data entries do not represent
this unreliability.
* As for leap seconds, civil time was not based on atomic time before
1972, and we don't know the history of earth's rotation accurately
enough to map SI seconds to historical solar time to more than
about one-hour accuracy. See: Morrison LV, Stephenson FR.
Historical values of the Earth's clock error Delta T and the
calculation of eclipses. J Hist Astron. 2004;35:327-36
<http://adsabs.harvard.edu/full/2004JHA....35..327M>;
Historical values of the Earth's clock error. J Hist Astron. 2005;36:339
<http://adsabs.harvard.edu/full/2005JHA....36..339M>.
* The relationship between POSIX time (that is, UTC but ignoring leap
seconds) and UTC is not agreed upon after 1972. Although the POSIX
clock officially stops during an inserted leap second, at least one
proposed standard has it jumping back a second instead; and in
practice POSIX clocks more typically either progress glacially during
a leap second, or are slightly slowed while near a leap second.
* The tz database does not represent how uncertain its information is.
Ideally it would contain information about when data entries are
incomplete or dicey. Partial temporal knowledge is a field of
active research, though, and it's not clear how to apply it here.
In short, many, perhaps most, of the tz database's pre-1970 and future
time stamps are either wrong or misleading. Any attempt to pass the
tz database off as the definition of time should be unacceptable to
anybody who cares about the facts. In particular, the tz database's
LMT offsets should not be considered meaningful, and should not prompt
creation of zones merely because two locations differ in LMT or
transitioned to standard time at different dates.
----- Time and date functions -----
The tz code contains time and date functions that are upwards
compatible with those of POSIX.
POSIX has the following properties and limitations.
* In POSIX, time display in a process is controlled by the
environment variable TZ. Unfortunately, the POSIX TZ string takes
a form that is hard to describe and is error-prone in practice.
Also, POSIX TZ strings can't deal with other (for example, Israeli)
daylight saving time rules, or situations where more than two
time zone abbreviations are used in an area.
The POSIX TZ string takes the following form:
stdoffset[dst[offset][,date[/time],date[/time]]]
where:
std and dst
are 3 or more characters specifying the standard
and daylight saving time (DST) zone names.
Starting with POSIX.1-2001, std and dst may also be
in a quoted form like "<UTC+10>"; this allows
"+" and "-" in the names.
offset
is of the form '[+-]hh:[mm[:ss]]' and specifies the
offset west of UT. 'hh' may be a single digit; 0<=hh<=24.
The default DST offset is one hour ahead of standard time.
date[/time],date[/time]
specifies the beginning and end of DST. If this is absent,
the system supplies its own rules for DST, and these can
differ from year to year; typically US DST rules are used.
time
takes the form 'hh:[mm[:ss]]' and defaults to 02:00.
This is the same format as the offset, except that a
leading '+' or '-' is not allowed.
date
takes one of the following forms:
Jn (1<=n<=365)
origin-1 day number not counting February 29
n (0<=n<=365)
origin-0 day number counting February 29 if present
Mm.n.d (0[Sunday]<=d<=6[Saturday], 1<=n<=5, 1<=m<=12)
for the dth day of week n of month m of the year,
where week 1 is the first week in which day d appears,
and '5' stands for the last week in which day d appears
(which may be either the 4th or 5th week).
Typically, this is the only useful form;
the n and Jn forms are rarely used.
Here is an example POSIX TZ string, for US Pacific time using rules
appropriate from 1987 through 2006:
TZ='PST8PDT,M4.1.0/02:00,M10.5.0/02:00'
This POSIX TZ string is hard to remember, and mishandles time stamps
before 1987 and after 2006. With this package you can use this
instead:
TZ='America/Los_Angeles'
* POSIX does not define the exact meaning of TZ values like "EST5EDT".
Typically the current US DST rules are used to interpret such values,
but this means that the US DST rules are compiled into each program
that does time conversion. This means that when US time conversion
rules change (as in the United States in 1987), all programs that
do time conversion must be recompiled to ensure proper results.
* In POSIX, there's no tamper-proof way for a process to learn the
system's best idea of local wall clock. (This is important for
applications that an administrator wants used only at certain times -
without regard to whether the user has fiddled the "TZ" environment
variable. While an administrator can "do everything in UTC" to get
around the problem, doing so is inconvenient and precludes handling
daylight saving time shifts - as might be required to limit phone
calls to off-peak hours.)
* POSIX requires that systems ignore leap seconds.
* The tz code attempts to support all the time_t implementations
allowed by POSIX. The time_t type represents a nonnegative count of
seconds since 1970-01-01 00:00:00 UTC, ignoring leap seconds.
In practice, time_t is usually a signed 64- or 32-bit integer; 32-bit
signed time_t values stop working after 2038-01-19 03:14:07 UTC, so
new implementations these days typically use a signed 64-bit integer.
Unsigned 32-bit integers are used on one or two platforms,
and 36-bit and 40-bit integers are also used occasionally.
Although earlier POSIX versions allowed time_t to be a
floating-point type, this was not supported by any practical
systems, and POSIX.1-2013 and the tz code both require time_t
to be an integer type.
These are the extensions that have been made to the POSIX functions:
* The "TZ" environment variable is used in generating the name of a file
from which time zone information is read (or is interpreted a la
POSIX); "TZ" is no longer constrained to be a three-letter time zone
name followed by a number of hours and an optional three-letter
daylight time zone name. The daylight saving time rules to be used
for a particular time zone are encoded in the time zone file;
the format of the file allows U.S., Australian, and other rules to be
encoded, and allows for situations where more than two time zone
abbreviations are used.
It was recognized that allowing the "TZ" environment variable to
take on values such as "America/New_York" might cause "old" programs
(that expect "TZ" to have a certain form) to operate incorrectly;
consideration was given to using some other environment variable
(for example, "TIMEZONE") to hold the string used to generate the
time zone information file name. In the end, however, it was decided
to continue using "TZ": it is widely used for time zone purposes;
separately maintaining both "TZ" and "TIMEZONE" seemed a nuisance;
and systems where "new" forms of "TZ" might cause problems can simply
use TZ values such as "EST5EDT" which can be used both by
"new" programs (a la POSIX) and "old" programs (as zone names and
offsets).
* To handle places where more than two time zone abbreviations are used,
the functions "localtime" and "gmtime" set tzname[tmp->tm_isdst]
(where "tmp" is the value the function returns) to the time zone
abbreviation to be used. This differs from POSIX, where the elements
of tzname are only changed as a result of calls to tzset.
* Since the "TZ" environment variable can now be used to control time
conversion, the "daylight" and "timezone" variables are no longer
needed. (These variables are defined and set by "tzset"; however, their
values will not be used by "localtime.")
* The "localtime" function has been set up to deliver correct results
for near-minimum or near-maximum time_t values. (A comment in the
source code tells how to get compatibly wrong results).
* A function "tzsetwall" has been added to arrange for the system's
best approximation to local wall clock time to be delivered by
subsequent calls to "localtime." Source code for portable
applications that "must" run on local wall clock time should call
"tzsetwall();" if such code is moved to "old" systems that don't
provide tzsetwall, you won't be able to generate an executable program.
(These time zone functions also arrange for local wall clock time to be
used if tzset is called - directly or indirectly - and there's no "TZ"
environment variable; portable applications should not, however, rely
on this behavior since it's not the way SVR2 systems behave.)
* Negative time_t values are supported, on systems where time_t is signed.
* These functions can account for leap seconds, thanks to Bradley White.
Points of interest to folks with other systems:
* This package is already part of many POSIX-compliant hosts,
including BSD, HP, Linux, Network Appliance, SCO, SGI, and Sun.
On such hosts, the primary use of this package
is to update obsolete time zone rule tables.
To do this, you may need to compile the time zone compiler
'zic' supplied with this package instead of using the system 'zic',
since the format of zic's input changed slightly in late 1994,
and many vendors still do not support the new input format.
* The UNIX Version 7 "timezone" function is not present in this package;
it's impossible to reliably map timezone's arguments (a "minutes west
of GMT" value and a "daylight saving time in effect" flag) to a
time zone abbreviation, and we refuse to guess.
Programs that in the past used the timezone function may now examine
tzname[localtime(&clock)->tm_isdst] to learn the correct time
zone abbreviation to use. Alternatively, use
localtime(&clock)->tm_zone if this has been enabled.
* The 4.2BSD gettimeofday function is not used in this package.
This formerly let users obtain the current UTC offset and DST flag,
but this functionality was removed in later versions of BSD.
* In SVR2, time conversion fails for near-minimum or near-maximum
time_t values when doing conversions for places that don't use UT.
This package takes care to do these conversions correctly.
The functions that are conditionally compiled if STD_INSPIRED is defined
should, at this point, be looked on primarily as food for thought. They are
not in any sense "standard compatible" - some are not, in fact, specified in
*any* standard. They do, however, represent responses of various authors to
standardization proposals.
Other time conversion proposals, in particular the one developed by folks at
Hewlett Packard, offer a wider selection of functions that provide capabilities
beyond those provided here. The absence of such functions from this package
is not meant to discourage the development, standardization, or use of such
functions. Rather, their absence reflects the decision to make this package
contain valid extensions to POSIX, to ensure its broad acceptability. If
more powerful time conversion functions can be standardized, so much the
better.
----- Calendrical issues -----
Calendrical issues are a bit out of scope for a time zone database,
but they indicate the sort of problems that we would run into if we
extended the time zone database further into the past. An excellent
resource in this area is Nachum Dershowitz and Edward M. Reingold,
Calendrical Calculations: Third Edition, Cambridge University Press (2008)
<http://emr.cs.iit.edu/home/reingold/calendar-book/third-edition/>.

France
Gregorian calendar adopted 1582-12-20.
French Revolutionary calendar used 1793-11-24 through 1805-12-31,
and (in Paris only) 1871-05-06 through 1871-05-23.
Russia
From Chris Carrier (1996-12-02):
On 1929-10-01 the Soviet Union instituted an "Eternal Calendar"
with 30-day months plus 5 holidays, with a 5-day week.
On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the
Gregorian calendar while retaining the 6-day week; on 1940-06-27 it
reverted to the 7-day week. With the 6-day week the usual days
off were the 6th, 12th, 18th, 24th and 30th of the month.

In 1700, Denmark made the transition from Julian to Gregorian. Sweden
decided to *start* a transition in 1700 as well, but rather than have one of
those unsightly calendar gaps :-), they simply decreed that the next leap
year after 1696 would be in 1744 - putting the whole country on a calendar
different from both Julian and Gregorian for a period of 40 years.
However, in 1704 something went wrong and the plan was not carried through;
they did, after all, have a leap year that year. And one in 1708. In 1712
they gave it up and went back to Julian, putting 30 days in February that
year!...
Then in 1753, Sweden made the transition to Gregorian in the usual manner,
getting there only 13 years behind the original schedule.
(A previous posting of this story was challenged, and Swedish readers
produced the following references to support it: "Tideräkning och historia"
by Natanael Beckman (1924) and "Tid, en bok om tideräkning och
kalenderväsen" by Lars-Olof Lodén (1968).

----- Time and time zones on Mars -----
Some people's work schedules use Mars time. Jet Propulsion Laboratory
(JPL) coordinators have kept Mars time on and off at least since 1997
for the Mars Pathfinder mission. Some of their family members have
also adapted to Mars time. Dozens of special Mars watches were built
for JPL workers who kept Mars time during the Mars Exploration
Rovers mission (2004). These timepieces look like normal Seikos and
Citizens but use Mars seconds rather than terrestrial seconds.
A Mars solar day is called a "sol" and has a mean period equal to
about 24 hours 39 minutes 35.244 seconds in terrestrial time. It is
divided into a conventional 24-hour clock, so each Mars second equals
about 1.02749125 terrestrial seconds.
The prime meridian of Mars goes through the center of the crater
Airy-0, named in honor of the British astronomer who built the
Greenwich telescope that defines Earth's prime meridian. Mean solar
time on the Mars prime meridian is called Mars Coordinated Time (MTC).
Each landed mission on Mars has adopted a different reference for
solar time keeping, so there is no real standard for Mars time zones.
For example, the Mars Exploration Rover project (2004) defined two
time zones "Local Solar Time A" and "Local Solar Time B" for its two
missions, each zone designed so that its time equals local true solar
time at approximately the middle of the nominal mission. Such a "time
zone" is not particularly suited for any application other than the
mission itself.
Many calendars have been proposed for Mars, but none have achieved
wide acceptance. Astronomers often use Mars Sol Date (MSD) which is a
sequential count of Mars solar days elapsed since about 1873-12-29
12:00 GMT.
The tz database does not currently support Mars time, but it is
documented here in the hopes that support will be added eventually.

# clocks go forward an hour at 2am to 3am.... Daylight Saving will
# end at 3.00am on Sunday 15th January 2017."
# From Paul Eggert (2017-08-21):
# Dominic Fok writes (2017-08-20) that DST ends 2018-01-14, citing
# Extraordinary Government of Fiji Gazette Supplement No. 21 (2017-08-27),
# [Legal Notice No. 41] of an order of the previous day by J Usamate.
# From Raymond Kumar (2018-07-13):
# http://www.fijitimes.com/government-approves-2018-daylight-saving/
# ... The daylight saving period will end at 3am on Sunday January 13, 2019.
#
# From Paul Eggert (2018-07-15):
# For now, guess DST from 02:00 the first Sunday in November to 03:00
# the first Sunday on or after January 13. January transitions reportedly
# depend on when school terms start. Although the guess is ad hoc, it matches
# transitions since late 2014 and seems more likely to match future
# practice than guessing no DST.

----- Calendrical issues -----
As mentioned in Theory.html, although calendrical issues are out of
scope for tzdb, they indicate the sort of problems that we would run
into if we extended tzdb further into the past. The following
information and sources go beyond Theory.html's brief discussion.
They sometimes disagree.
France
Gregorian calendar adopted 1582-12-20.
French Revolutionary calendar used 1793-11-24 through 1805-12-31,
and (in Paris only) 1871-05-06 through 1871-05-23.
Russia
From Chris Carrier (1996-12-02):
On 1929-10-01 the Soviet Union instituted an "Eternal Calendar"
with 30-day months plus 5 holidays, with a 5-day week.
On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the
Gregorian calendar while retaining the 6-day week; on 1940-06-27 it
reverted to the 7-day week. With the 6-day week the usual days
off were the 6th, 12th, 18th, 24th and 30th of the month.
(Source: Evitiar Zerubavel, _The Seven Day Circle_)
Mark Brader reported a similar story in "The Book of Calendars", edited
by Frank Parise (1982, Facts on File, ISBN 0-8719-6467-8), page 377. But:

If your source is correct, how come documents between 1929 and 1940 were
still dated using the conventional, Gregorian calendar?
I can post a scan of a document dated December 1, 1934, signed by
Yenukidze, the secretary, on behalf of Kalinin, the President of the
Executive Committee of the Supreme Soviet, if you like.

Subject: Re: Gregorian reform - a part of locale?
<news:1996Jul6.012937.29190@sq.com>
Date: 1996-07-06
In 1700, Denmark made the transition from Julian to Gregorian. Sweden
decided to *start* a transition in 1700 as well, but rather than have one of
those unsightly calendar gaps :-), they simply decreed that the next leap
year after 1696 would be in 1744 - putting the whole country on a calendar
different from both Julian and Gregorian for a period of 40 years.
However, in 1704 something went wrong and the plan was not carried through;
they did, after all, have a leap year that year. And one in 1708. In 1712
they gave it up and went back to Julian, putting 30 days in February that
year!...
Then in 1753, Sweden made the transition to Gregorian in the usual manner,
getting there only 13 years behind the original schedule.
(A previous posting of this story was challenged, and Swedish readers
produced the following references to support it: "Tideräkning och historia"
by Natanael Beckman (1924) and "Tid, en bok om tideräkning och
kalenderväsen" by Lars-Olof Lodén (1968).

# was the result of his proposals at the Convention of Railroad Trunk Lines
# in New York City (1869-10). His 1870 proposal was based on Washington, DC,
# but in 1872-05 he moved the proposed origin to Greenwich.
# His proposal was adopted by the railroads on 1883-11-18 at 12:00,
# and the most of the country soon followed suit.
# From Paul Eggert (2018-03-20):
# Dowd's proposal left many details unresolved, such as where to draw
# lines between time zones. The key individual who made time zones
# work in the US was William Frederick Allen - railway engineer,
# managing editor of the Travelers' Guide, and secretary of the
# General Time Convention, a railway standardization group. Allen
# spent months in dialogs with scientific and railway leaders,
# developed a workable plan to institute time zones, and presented it
# to the General Time Convention on 1883-04-11, saying that his plan
# meant "local time would be practically abolished" - a plus for
# railway scheduling. By the next convention on 1883-10-11 nearly all
# railroads had agreed and it took effect on 1883-11-18. That Sunday
# was called the "day of two noons", as some locations observed noon
# twice. Allen witnessed the transition in New York City, writing:
#
# I heard the bells of St. Paul's strike on the old time. Four
# minutes later, obedient to the electrical signal from the Naval
# Observatory ... the time-ball made its rapid descent, the chimes
# of old Trinity rang twelve measured strokes, and local time was
# abandoned, probably forever.

# Although Shanks says Detroit observed DST in 1967 from 06-14 00:01
# until 10-29 00:01, I now see multiple reports that this is incorrect.
# For example, according to a 50-year anniversary report about the 1967
# Detroit riots and a major-league doubleheader on 1967-07-23, "By the time
# the last fly ball of the doubleheader settled into the glove of leftfielder
# Lenny Green, it was after 7 p.m. Detroit did not observe daylight saving
# time, so light was already starting to fail. Twilight was made even deeper
# by billowing columns of smoke that ascended in an unbroken wall north of the
# ballpark." See: Dow B. Detroit '67: As violence unfolded, Tigers played two
# at home vs. Yankees. Detroit Free Press 2017-07-23.
