lib::Time::ParsUsereContributed Perl Documlib::Time::ParseDate(3)NAMETime::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.

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 contect, 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, $remaining) = parsedate("today is the day");
($seconds, $error) = parsedate("today is", WHOLE=>1);
