Time::Zone -- miscellaneous timezone manipulations routines
SYNOPSIS
use Time::Zone;
print tz2zone();
print tz2zone($ENV{'TZ'});
print tz2zone($ENV{'TZ'}, time());
print tz2zone($ENV{'TZ'}, undef, $isdst);
$offset = tz_local_offset();
$offset = tz_offset($TZ);
DESCRIPTION
This is a collection of miscellaneous timezone manipulation routines.
"tz2zone()" parses the TZ environment variable and returns a timezone string suitable for inclusion in date(1)-like output. It opionally
takes a timezone string, a time, and a is-dst flag.
"tz_local_offset()" determins the offset from GMT time in seconds. It only does the calculation once.
"tz_offset()" determines the offset from GMT in seconds of a specified timezone.
"tz_name()" determines the name of the timezone based on its offset

Time::ParseDate(3) User Contributed Perl Documentation Time::ParseDate(3)NAME
Time::ParseDate -- date parsing both relative and absolute
SYNOPSIS
use Time::ParseDate;
$seconds_since_jan1_1970 = parsedate("12/11/94 2pm", NO_RELATIVE => 1)
$seconds_since_jan1_1970 = parsedate("12/11/94 2pm", %options)
OPTIONS
Date parsing can also use options. The options are as follows:
FUZZY -> it's okay not to parse the entire date string
NOW -> the "current" time for relative times (defaults to time())
ZONE -> local timezone (defaults to $ENV{TZ})
WHOLE -> the whole input string must be parsed
GMT -> input time is assumed to be GMT, not localtime
UK -> prefer UK style dates (dd/mm over mm/dd)
DATE_REQUIRED -> do not default the date
TIME_REQUIRED -> do not default the time
NO_RELATIVE -> input time is not relative to NOW
TIMEFIRST -> try parsing time before date [not default]
PREFER_PAST -> when year or day of week is ambigueous, assume past
PREFER_FUTURE -> when year or day of week is ambigueous, assume future
SUBSECOND -> parse fraction seconds
VALIDATE -> only accept normal values for HHMMSS, YYMMDD. Otherwise
days like -1 might give the last day of the previous month.

yyyy/mm
mm/dd/yy
mm/dd/yyyy
mm/yy
yy/mm (only if year > 12, or > 31 if UK)
yy/mm/dd (only if year > 12 and day < 32, or year > 31 if UK)
dd/mm/yy (only if UK, or an invalid mm/dd/yy or yy/mm/dd)
dd/mm/yyyy (only if UK, or an invalid mm/dd/yyyy)
dd/mm (only if UK, or an invalid mm/dd)
Relative date formats:
count "days"
count "weeks"
count "months"
count "years"
Dow "after next"
Dow "before last"
Dow (requires PREFER_PAST or PREFER_FUTURE)
"next" Dow

Special formats:

yy/mm/dd.hh:mm
DESCRIPTION
This module recognizes the above date/time formats. Usually a date and a time are specified. There are numerous options for controlling
what is recognized and what is not.
The return code is always the time in seconds since January 1st, 1970 or undef if it was unable to parse the time.
If a timezone is specified it must be after the time. Year specifications can be tacked onto the end of absolute times.
If "parsedate()" is called from array context, then it will return two elements. On sucessful parses, it will return the seconds and what
remains of its input string. On unsucessful parses, it will return "undef" and an error string.
EXAMPLES
$seconds = parsedate("Mon Jan 2 04:24:27 1995");
$seconds = parsedate("Tue Apr 4 00:22:12 PDT 1995");
$seconds = parsedate("04.04.95 00:22", ZONE => PDT);
$seconds = parsedate("Jan 1 1999 11:23:34.578", SUBSECOND => 1);
$seconds = parsedate("122212 950404", ZONE => PDT, TIMEFIRST => 1);
$seconds = parsedate("+3 secs", NOW => 796978800);
$seconds = parsedate("2 months", NOW => 796720932);
$seconds = parsedate("last Tuesday");
$seconds = parsedate("Sunday before last");
($seconds, $remaining) = parsedate("today is the day");
($seconds, $error) = parsedate("today is", WHOLE=>1);
