A time of 24:00 or more appears in the input.
|
|
|
|
Pre-1998 versions of
|
|
|
|
.B zic
|

prohibit 24:00, and pre-2007 versions prohibit times greater than 24:00.

A rule goes past the start or end of the month.

Pre-2004 versions of

.PP
|

|
The output file does not contain all the information about the
|
|
|
|
long-term future of a timezone, because the future cannot be summarized as
|
|
|
|
an extended POSIX TZ string. For example, as of 2013 this problem
|
|
|
|
occurs for Iran's daylight-saving rules for the predicted future, as
|
|
|
|
these rules are based on the Iranian calendar, which cannot be
|
|
|
|
represented.
|
|
|
|
.PP
|
|

The output contains data that may not be handled properly by client
|
|
|
|
code designed for older
|
|
|
|
.B zic
|
|
|
|
output formats. These compatibility issues affect only timestamps
|
|
|
|
before 1970 or after the start of 2038.

A time zone abbreviation has fewer than 3 characters.

An output file name contains a byte that is not an ASCII letter,

.q "/" ,
|

or

.B \*-s

2004-11-03 13:51:07 +00:00

Limit time values stored in output files to values that are the same
|
|
|
|
whether they're taken to be signed or unsigned.
|
|
|

You can use this option to generate SVVS-compatible files.

Input files should be text files, that is, they should be a series of
|
|
|
|
zero or more lines, each ending in a newline byte and containing at
|
|
|
|
most 511 bytes, and without any NUL bytes. The input text's encoding
|
|
|
|
is typically UTF-8 or ASCII; it should have a unibyte representation
|
|
|
|
for the POSIX Portable Character Set (PPCS)
|
|
|
|
\*<http://pubs\*:.opengroup\*:.org/\*:onlinepubs/\*:9699919799/\*:basedefs/\*:V1_chap06\*:.html\*>
|
|
|
|
and the encoding's non-unibyte characters should consist entirely of
|
|
|
|
non-PPCS bytes. Non-PPCS characters typically occur only in comments:
|
|
|
|
although output file names and time zone abbreviations can contain
|
|
|
|
nearly any character, other software will work better if these are
|
|
|
|
limited to the restricted syntax described under the
|
|
|
|
.B \*-v
|
|
|

option.

Input lines are made up of fields.
|
2018-06-27 19:52:37 +00:00
|
|
|
Fields are separated from one another by one or more white space characters.
|
|
|
|
The white space characters are space, form feed, carriage return, newline,
|
|
|
|
tab, and vertical tab.
|
2004-11-03 13:51:07 +00:00
|
|
|
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.
|
2010-01-16 17:02:43 +00:00
|
|
|
Nonblank lines are expected to be of one of three types:
|
2004-11-03 13:51:07 +00:00
|
|
|
rule lines, zone lines, and link lines.
|

2018-06-27 19:52:37 +00:00

Names must be in English and are case insensitive.
|
|
|
|
They appear in several contexts, and include month and weekday names
|
|
|
|
and keywords such as
|
|
|
|
.BR "maximum" ,
|
|
|
|
.BR "only" ,
|

.BR "Rolling" ,
|

|
|
and
|
|
|

.BR "Zone" .
|

A name can be abbreviated by omitting all but an initial prefix; any
|
|
|
|
abbreviation must be unambiguous in context.

|
|
|
|
.B NAME
|
2018-06-27 19:52:37 +00:00

Gives the name of the rule set that contains this line.

The name must start with a character that is neither

an ASCII digit nor
|
|
|

.q \*-

an unquoted name should not contain characters from the set

Rules can describe times that are not representable as time values,
|
|
|
|
with the unrepresentable times ignored; this allows rules to be portable
|

|

among hosts with differing time value types.

giving of the amount of time to be added to local standard time

The format for time zone abbreviations.

|
|
|
The pair of characters
|
|
|

is used to show where the

|
|

.q "variable part"

|
|
|

Alternatively, a format can use the pair of characters
|
|
|
|
.B %z
|

|
to stand for the UT offset in the form
|
|
|
|
.RI \(+- hh ,

|
|

.IR mm ,

are the hours, minutes, and seconds east (+) or west (\(mi) of UT.

Alternatively,

2004-11-03 13:51:07 +00:00

a slash (/)
|

separates standard and daylight abbreviations.

The time at which the UT offset or the rule(s) change for a location.
|
|
|
|
It takes the form of YEAR [MONTH [DAY [TIME]]].
|
2004-11-03 13:51:07 +00:00
|
|

If this is specified,
|
2018-06-27 19:52:37 +00:00

the time zone information is generated from the given UT offset
|
|

the rules in effect just before the transition.

Continuation lines may contain

If a zone changes at the same instant that a rule would otherwise take

effect in the earlier zone or continuation line, the rule is ignored.

In a single zone it is an error if two rules take effect at the same

instant, or if two zone changes take effect at the same instant.

In this example, the timezone is named Europe/Zurich but it has an alias
|
|
|
|
as Europe/Vaduz. This example says that Zurich was 34 minutes and 8
|
|
|
|
seconds east of UT until 1853-07-16 at 00:00, when the legal offset
|
|
|
|
was changed to 7\(de\|26\(fm\|22.50\(sd; although this works out to
|
|
|
|
0:29:45.50, the input format cannot represent fractional seconds so it
|
|
|
|
is rounded here. After 1894-06-01 at 00:00 the UT offset became one hour
|
|
|
|
and Swiss daylight saving rules (defined with lines beginning with
|
|
|
|
.q "Rule Swiss")
|
|
|
|
apply. From 1981 to the present, EU daylight saving rules have
|
|
|
|
applied, and the UTC offset has remained at one hour.
|
|
|
|
.PP
|
|
|
|
In 1941 and 1942, daylight saving time applied from the first Monday
|
|
|
|
in May at 01:00 to the first Monday in October at 02:00.
|
|
|
|
The pre-1981 EU daylight-saving rules have no effect
|
|
|
|
here, but are included for completeness. Since 1981, daylight
|
|
|
|
saving has begun on the last Sunday in March at 01:00 UTC.
|
|
|
|
Until 1995 it ended the last Sunday in September at 01:00 UTC,
|
|
|
|
but this changed to the last Sunday in October starting in 1996.

For purposes of display,

|
|
.q "LMT"
|
|
|
|
and
|
|
|
|
.q "BMT"
|
|
|
|
were initially used, respectively. Since
|
|
|
|
Swiss rules and later EU rules were applied, the time zone abbreviation
|
|
|
|
has been CET for standard time and CEST for daylight saving
|
|
|
|
time.

2004-11-03 13:51:07 +00:00
|
|
|
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.

|
|
|
|
If,
|
|
|
|
for a particular timezone,
|
|
|
|
a clock advance caused by the start of daylight saving
|
|
|
|
coincides with and is equal to
|
|
|
|
a clock retreat caused by a change in UT offset,
|
|
|
|
.B zic
|
|
|
|
produces a single transition to daylight saving at the new UT offset
|
|
|
|
(without any change in wall clock time).
|
|
|
|
To get separate transitions
|
|
|
|
use multiple zone continuation lines
|
|
|
|
specifying transition instants using universal time.
