@(#)README 3.2 1996/11/29
Please send comments or information to
seismo!elsie!tz
for forwarding to folks interested in time zone matters.
Be sure to read the comments in "Makefile" and make any changes
needed to make things right for your system.
This version of the time zone software uses a new format
(based on the work of Guy Harris, a.k.a guy@sun.UUCP)
for the time zone information files. They are stored in a
directory named "/usr/share/zoneinfo".
If you've already compiled programs with older time zone software,
you may need to make a copy of /usr/share/zoneinfo to the old location.
For better compatability with other versions of time conversion functions,
the time zone abbreviation to be used with localtime's return value is now
pointed to by one of the two elements of the (char *) array tzname, rather
than by the (char *) tz_abbr. If you have code that uses tz_abbr, add a
-DTZA_COMPAT
to the end of the
CFLAGS=
line in "Makefile".
To use the new functions, use a "-lz" option when compiling or linking.
Historical local time information has been included here not because it
is particularly useful, but rather to:
* give an idea of the variety of local time rules that have
existed in the past and thus an idea of the variety that may be
expected in the future;
* provide a test of the generality of the local time rule description
system.
The information in the time zone data files is by no means authoritative;
if you know that the rules are different from those in a file, by all means
feel free to change file (and please send the changed version to seismo!elsie!tz
for use in the future). Europeans take note!

@(#)Theory 3.2 1996/11/29
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 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
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
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 GMT" to get
around the problem, doing so is inconvenient and precludes handling
daylight savings time shifts--as might be required to limit phone
calls to off-peak hours.)
These are the changes that have been made to the SVR2 functions:
* The "TZ" environment variable is used in generating the name of a file
from which time zone information is read; "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 "US/Eastern" 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
give time zone files names such as "EST5EDT" which can be used both by
"new" programs (as file names) 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 SVR2, 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 or supported. (You can use a compile-time option to cause
these variables to be defined and to be 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.)
Points of interest to folks with Version 7 or BSD systems:
* The BSD "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 BSD gettimeofday function is not used in this package;
this lets users control the time zone used in doing time conversions.
Users who don't try to control things (that is, users who do not set
the environment variable TZ) get the time conversion specified in the
file "/etc/localtime"; see the time zone compiler writeup for
information on how to initialize this file.
* The BSD "dysize" function is only included if the preprocessor symbol
BSD_COMPAT is defined. For a year y, the BSD code returns the value
((y % 4) == 0) : 366 : 365
while this code returns the value
(((y) % 4) == 0 && ((y) % 100) != 0 || ((y) % 400) == 0) ? 366 : 365
There's a comment in the code telling how to get the BSD value.
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
close to SVR2 (with the exceptions outlined above) to ensure its broad
acceptability. If more powerful time conversion functions can be standardized,
so much the better.
It's probably not wise to standardize everything in this package.
While the command
nroff -man newctime.3
produces a document that describes this package, the command
nroff -man -rX3J11 newctime.3
produces a document that describes the "standardizable" parts.

# ...the European time rules are...standardized since 1981, when
# most European counrties started DST. Before that year, only
# a few countries (UK, France, Italy) had DST, each according
# to own national rules. In 1981, however, DST started on
# 'Apr firstSun', and not on 'Mar lastSun' as in the following
# years...
# But also since 1981 there are some more national exceptions
# than listed in 'europe': Switzerland, for example, joined DST
# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
# lastSun' in 1981---I don't know how they handle now.
#
# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the

# Message-Id: <8702042135.AA23919@zuring.cwi.nl>
# ...
# Subject: timezones
# ...
#
# The information from Tom Hofmann is (as far as I know) not entirely correct.
# After a request from chongo at amdahl I tried to retrieve all information
# about DST in Europe. I was able to find all from about 1969.
#
# ...standardization
# on DST in Europe started in about 1977 with switches on first Sunday in
# April and last Sunday in September. In UK it was from last but 1 Sunday
# in march to last Sunday in October. In 1981 UK joined Europe insofar that
# the starting day for both shifted to last Sunday in March. And from 1982
# the whole of Europe used DST, with switch dates April 1 and October 1 in
# the Sovjet Union. In 1985 the SU reverted to standard Europen switch
# dates. Note that currently in the UK the switch back date appears not
# to be the last Sunday in October, but 4 weeks after the last Sunday in
# September (withness 1982 and 1983 with terminating days October 24 and 23).
#
# It should also be remembered that time-zones are not constants; e.g.
# Portugal switched in 1976 from MET (or CET) to WET with DST, and the UK
# used MET throughout from 1967 to 1969, and WET with DST before and after
# that time. Note also that though there were rules for switch dates not
# all countries abided to these dates, and many individual deviations
# occurred, though not since 1982 I believe. Another note: it is always
# assumed that DST is 1 hour ahead of normal time, this need not be the
# case; at least in the Netherlands there have been times when DST was 2 hours
# in advance of normal time.

# @(#)solar87 3.1
# So much for footnotes about Saudi Arabia.
# Apparent noon times below are for Riyadh; your mileage will vary.
# Times were computed using formulas in the U.S. Naval Observatory's
# Almanac for Computers 1987; the formulas "will give EqT to an accuracy of
# [plus or minus] two seconds during the current year."
#
# Rounding to the nearest five seconds results in fewer than
# 256 different "time types"--a limit that's faced because time types are

.TH ZIC 8
.SH NAME
zic \- time zone compiler
.SH SYNOPSIS
.B zic
[
.B \-v
] [
.B \-d
.I directory
] [
.B \-l
.I localtime
] [
.I filename
\&... ]
.SH DESCRIPTION
.I Zic
reads text from the file(s) named on the command line
and creates the time conversion information files specified in this input.
If a
.I filename
is
.BR \- ,
the standard input is read.
.PP
These options are available:
.TP
.BI "\-d " directory
Create time conversion information files in the named directory rather than
in the standard directory named below.
.TP
.BI "\-l " timezone
Use the given time zone as local time.
.I Zic
will act as if the file contained a link line of the form
.sp
.ti +.5i
Link \fItimezone\fP localtime
.TP
.B \-v
Complain if a year that appears in a data file is outside the range
of years representable by
.IR time (2)
values.
.sp
Input lines are made up of fields.
Fields are separated from one another by any number of white space characters.
Leading and trailing white space on input lines is ignored.
An unquoted sharp character (#) in the input introduces a comment which extends
to the end of the line the sharp character appears on.
White space characters and sharp characters may be enclosed in double quotes
(") if they're to be used as part of a field.
Any line that is blank (after comment stripping) is ignored.
Non-blank lines are expected to be of one of three types:
rule lines, zone lines, and link lines.
.PP
A rule line has the form
.nf
.B
.ti +.5i
.ta \w'Rule\0\0'u +\w'NAME\0\0'u +\w'FROM\0\0'u +\w'1973\0\0'u +\w'TYPE\0\0'u +\w'Apr\0\0'u +\w'lastSun\0\0'u +\w'2:00\0\0'u +\w'SAVE\0\0'u
.sp
Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S
.sp
For example:
.ti +.5i
.sp
Rule USA 1969 1973 \- Apr lastSun 2:00 1:00 D
.sp
.fi
The fields that make up a rule line are:
.TP "\w'LETTER/S'u"
.B NAME
Gives the (arbitrary) name of the set of rules this rule is part of.
.TP
.B FROM
Gives the first year in which the rule applies.
The word
.B minimum
(or an abbreviation) means the minimum year with a representable time value.
The word
.B maximum
(or an abbreviation) means the maximum year with a representable time value.
.TP
.B TO
Gives the final year in which the rule applies.
In addition to
.B minimum
and
.B maximum
(as above),
the word
.B only
(or an abbreviation)
may be used to repeat the value of the
.B FROM
field.
.TP
.B TYPE
Gives the type of year in which the year applies.
If
.B TYPE
is
.B \-
then the rule applies in all years between
.B FROM
and
.B TO
inclusive;
if
.B TYPE
is
.BR uspres ,
the rule applies in U.S. Presidential election years;
if
.B TYPE
is
.BR nonpres ,
the rule applies in years other than U.S. Presidential election years.
If
.B TYPE
is something else, then
.I zic
executes the command
.ti +.5i
\fByearistype\fP \fIyear\fP \fItype\fP
.br
to check the type of a year:
an exit status of zero is taken to mean that the year is of the given type;
an exit status of one is taken to mean that the year is not of the given type.
.TP
.B IN
Names the month in which the rule takes effect.
Month names may be abbreviated.
.TP
.B ON
Gives the day on which the rule takes effect.
Recognized forms include:
.nf
.in +.5i
.sp
.ta \w'Sun<=25\0\0'u
5 the fifth of the month
lastSun the last Sunday in the month
lastMon the last Monday in the month
Sun>=8 first Sunday on or after the eighth
Sun<=25 last Sunday on or before the 25th
.fi
.in -.5i
.sp
Names of days of the week may be abbreviated or spelled out in full.
Note that there must be no spaces within the
.B ON
field.
.TP
.B AT
Gives the time of day at which the rule takes affect.
Recognized forms include:
.nf
.in +.5i
.sp
.ta \w'1:28:13\0\0'u
2 time in hours
2:00 time in hours and minutes
15:00 24-hour format time (for times after noon)
1:28:14 time in hours, minutes, and seconds
.fi
.in -.5i
.sp
Any of these forms may be followed by the letter
.B w
if the given time is local ``wall clock'' time or
.B s
if the given time is local ``standard'' time; in the absence of
.B w
or
.BR s ,
wall clock time is assumed.
.TP
.B SAVE
Gives the amount of time to be added to local standard time when the rule is in
effect.
This field has the same format as the
.B AT
field
(although, of course, the
.B w
and
.B s
suffixes are not used).
.TP
.B LETTER/S
Gives the ``variable part'' (for example, the ``S'' or ``D'' in ``EST''
or ``EDT'') of time zone abbreviations to be used when this rule is in effect.
If this field is
.BR \- ,
the variable part is null.
.PP
A zone line has the form
.sp
.nf
.ti +.5i
.ta \w'Zone\0\0'u +\w'Australia/South\-west\0\0'u +\w'GMTOFF\0\0'u +\w'RULES/SAVE\0\0'u +\w'FORMAT\0\0'u
Zone NAME GMTOFF RULES/SAVE FORMAT [UNTIL]
.sp
For example:
.sp
.ti +.5i
Zone Australia/South\-west 9:30 Aus CST 1987 Mar 15 2:00
.sp
.fi
The fields that make up a zone line are:
.TP "\w'GMTOFF'u"
.B NAME
The name of the time zone.
This is the name used in creating the time conversion information file for the
zone.
.TP
.B GMTOFF
The amount of time to add to GMT to get standard time in this zone.
This field has the same format as the
.B AT
and
.B SAVE
fields of rule lines;
begin the field with a minus sign if time must be subtracted from GMT.
.TP
.B RULES/SAVE
The name of the rule(s) that apply in the time zone or,
alternately, an amount of time to add to local standard time.
If this field is
.B \-
then standard time always applies in the time zone.
.TP
.B FORMAT
The format for time zone abbreviations in this time zone.
The pair of characters
.B %s
is used to show where the ``variable part'' of the time zone abbreviation goes.
.B UNTIL
The time at which the GMT offset or the rule(s) change for a location.
It is specified as a year, a month, a day, and a time of day.
If this is specified,
the time zone information is generated from the given GMT offset
and rule change until the time specified.
.IP
The next line must be a
``continuation'' line; this has the same form as a zone line except that the
string ``Zone'' and the name are omitted, as the continuation line will
place information starting at the time specified as the
.B UNTIL
field in the previous line in the file used by the previous line.
Continuation lines may contain an
.B UNTIL
field, just as zone lines do, indicating that the next line is a further
continuation.
.PP
A link line has the form
.sp
.nf
.ti +.5i
.if t .ta \w'Link\0\0'u +\w'LINK-FROM\0\0'u
.if n .ta \w'Link\0\0'u +\w'US/Eastern\0\0'u
Link LINK-FROM LINK-TO
.sp
For example:
.sp
.ti +.5i
Link US/Eastern EST5EDT
.sp
.fi
The
.B LINK-FROM
field should appear as the
.B NAME
field in some zone line;
the
.B LINK-TO
field is used as an alternate name for that zone.
.PP
Except for continuation lines,
lines may appear in any order in the input.
.SH NOTE
For areas with more than two types of local time,
you may need to use local standard time in the
.B AT
field of the earliest transition time's rule to ensure that
the earliest transition time recorded in the compiled file is correct.
