Notes: Wall-clock time plays a central role in the plot.

European readers of the 1870s clearly held the U.S. press in
|

deep contempt; the protagonists cross the U.S. without once
|

reading a paper.

These time and date functions are much like the System V Release 2.0 (SVR2)
|
||||
time and date functions; there are a few additions and changes to extend
|
||||
the usefulness of the SVR2 functions:
|
||||
|
||||
* In SVR2, time display in a process is controlled by the environment
|
||||
variable TZ, which "must be a three-letter time zone name, followed
|
||||
by a number representing the difference between local time and
|
||||
Greenwich Mean Time in hours, followed by an optional three-letter
|
||||
name for a daylight time zone;" when the optional daylight time zone is
|
||||
present, "standard U.S.A. Daylight Savings Time conversion is applied."
|
||||
This means that SVR2 can't deal with other (for example, Australian)
|
||||
daylight savings time rules, or situations where more than two

|

----- Time and date functions -----
|
||||
|
||||
These time and date functions are upwards compatible with POSIX.1,
|
||||
an international standard for Unix-like systems.
|
||||
As of this writing, the current edition of POSIX.1 is:
|
||||
|
||||
Information technology --Portable Operating System Interface (POSIX (R))
|
||||
-- Part 1: System Application Program Interface (API) [C Language]
|
||||
ISO/IEC 9945-1:1996
|
||||
ANSI/IEEE Std 1003.1, 1996 Edition
|
||||
1996-07-12
|
||||
|
||||
POSIX.1 has the following properties and limitations.
|
||||
|
||||
* In POSIX.1, time display in a process is controlled by the
|
||||
environment variable TZ. Unfortunately, the POSIX.1 TZ string takes
|
||||
a form that is hard to describe and is error-prone in practice.
|
||||
Also, POSIX.1 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.
|
||||
|
||||
* In SVR2, time conversion information is compiled into each program
|
||||
that does time conversion. This means that when time conversion
|
||||
The POSIX.1 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.
|
||||
offset
|
||||
is of the form `[-]hh:[mm[:ss]]' and specifies the
|
||||
offset west of UTC. 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.
|
||||
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).
|
||||
|
||||
* In POSIX.1, when a TZ value like "EST5EDT" is parsed,
|
||||
typically the current US DST rules are used,
|
||||
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 SVR2, time conversion fails for near-minimum or near-maximum
|
||||
time_t values when doing conversions for places that don't use GMT.
|
||||
|

* In SVR2, there's no tamper-proof way for a process to learn the

|
||||
----- Names of time zone rule files -----
|
||||
|
||||
The names of this package's installed time zone rule files are chosen to
|
||||
help minimize possible future incompatibilities due to political events.
|
||||
Ordinarily, names of countries are 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).
|
||||
|
||||
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 names. Use only Ascii letters, digits, `.',
|
||||
`-' and `_'. Do not exceed 14 characters or start with `-'.
|
||||
E.g. prefer `Brunei' to `Bandar_Seri_Begawan'.
|
||||
Include at least one location per time zone rule set per country.
|
||||
One such location is enough.
|
||||
If all the clocks in a country's 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 Jose 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 traditional English spelling, e.g. prefer `Rome' to `Roma', and
|
||||
prefer `Athens' to the true name (which uses Greek letters).
|
||||
The Posix file name restrictions encourage this rule.
|
||||
Use the most populous among locations in a country's time 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'.
|
||||
|
||||
The file `zone.tab' lists the geographical locations used to name
|
||||
time zone rule files.
|
||||
|
||||
Older versions of this package used a different naming scheme,
|
||||
and these older names are still supported.
|
||||
See the file `backwards' 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', `EET' (see the file `europe'),
|
||||
and `Factory' (see the file `factory').
|
||||
|
||||
|
||||
----- Time zone abbreviations -----
|
||||
|
||||
When this package is installed, it generates time zone abbreviations
|
||||
like `EST' to be compatible with human tradition and POSIX.1.
|
||||
Here are the general rules used for choosing time zone abbreviations,
|
||||
in decreasing order of importance:
|
||||
|
||||
Use abbreviations that consist of 3 or more upper-case Ascii letters,
|
||||
except use "___" for locations while uninhabited.
|
||||
Posix.1 requires at least 3 characters, and the restriction to
|
||||
upper-case Ascii letters follows most traditions.
|
||||
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. In theory, the character set could
|
||||
be !%./@A-Z^_a-z{}, but these tables use only upper-case
|
||||
Ascii letters (and "___").
|
||||
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'.
|
||||
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 has a single or principal time zone region,
|
||||
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.
|
||||
When a country has multiple time zones, take the first three
|
||||
letters of an English place name identifying each zone
|
||||
and then append `T', `ST', etc. as before;
|
||||
e.g. `VLAST' for VLAdivostok Summer Time.
|
||||
|
||||
Application writers should note that these abbreviations are ambiguous
|
||||
in practice: e.g. `EST' has a different meaning in Australia than
|
||||
it does in the United States. In new applications, it's often better
|
||||
to use numeric UTC offsets like `-0500' instead of time zone
|
||||
abbreviations like `EST'; this avoids the ambiguity.

The public-domain tz database contains code and data
|
||||
that represent the history of local time
|
||||
for many representative locations around the globe.
|
||||
It is updated periodically to reflect changes made by political bodies
|
||||
to UTC offsets and daylight-saving rules.
|
||||
This database (often called <samp>zoneinfo</samp>)
|
||||
is used by several implementations,
|
||||
including BSD, DJGPP, GNU/Linux, HP-UX, IRIX, Solaris, and UnixWare.
|
||||
In the tz database's
|
||||
<A HREF="ftp://elsie.nci.nih.gov/pub/">FTP distribution</A>,
|
||||
the code is in the file <samp>tzcode<var>C</var>.tar.gz</samp>,
|

where <samp><var>C</var></samp> is the code's version;
|
||||
similarly, the data are in <samp>tzdata<var>D</var>.tar.gz</samp>,

where <samp><var>D</var></samp> is the data's version.
