NAME

6       Time::ParseDate -- date parsing both relative and absolute
7

SYNOPSIS

9               use Time::ParseDate;
10               $seconds_since_jan1_1970 = parsedate("12/11/94 2pm", NO_RELATIVE => 1)
11               $seconds_since_jan1_1970 = parsedate("12/11/94 2pm", %options)

OPTIONS

14       Date parsing can also use options.  The options are as follows:
15
16               FUZZY   -> it's okay not to parse the entire date string
17               NOW     -> the "current" time for relative times (defaults to time())
18               ZONE    -> local timezone (defaults to $ENV{TZ})
19               WHOLE   -> the whole input string must be parsed
20               GMT     -> input time is assumed to be GMT, not localtime
21               UK      -> prefer UK style dates (dd/mm over mm/dd)
22               DATE_REQUIRED -> do not default the date
23               TIME_REQUIRED -> do not default the time
24               NO_RELATIVE -> input time is not relative to NOW
25               TIMEFIRST -> try parsing time before date [not default]
26               PREFER_PAST -> when year or day of week is ambiguous, assume past
27               PREFER_FUTURE -> when year or day of week is ambiguous, assume future
28               SUBSECOND -> parse fraction seconds
29               VALIDATE -> only accept normal values for HHMMSS, YYMMDD.  Otherwise
30                       days like -1 might give the last day of the previous month.

DESCRIPTION

105       This module recognizes the above date/time formats.   Usually a date
106       and a time are specified.  There are numerous options for controlling
107       what is recognized and what is not.
108
109       The return code is always the time in seconds since January 1st, 1970
110       or undef if it was unable to parse the time.
111
112       If a timezone is specified it must be after the time.  Year
113       specifications can be tacked onto the end of absolute times.
114
115       If "parsedate()" is called from array context, then it will return two
116       elements.  On successful parses, it will return the seconds and what
117       remains of its input string.  On unsuccessful parses, it will return
118       "undef" and an error string.

EXAMPLES

121               $seconds = parsedate("Mon Jan  2 04:24:27 1995");
122               $seconds = parsedate("Tue Apr 4 00:22:12 PDT 1995");
123               $seconds = parsedate("04.04.95 00:22", ZONE => PDT);
124               $seconds = parsedate("Jan 1 1999 11:23:34.578", SUBSECOND => 1);
125               $seconds = parsedate("122212 950404", ZONE => PDT, TIMEFIRST => 1);
126               $seconds = parsedate("+3 secs", NOW => 796978800);
127               $seconds = parsedate("2 months", NOW => 796720932);
128               $seconds = parsedate("last Tuesday");
129               $seconds = parsedate("Sunday before last");
130
131               ($seconds, $remaining) = parsedate("today is the day");
132               ($seconds, $error) = parsedate("today is", WHOLE=>1);
