NAME
Date::Parse - Parse date strings into time values
SYNOPSIS
use Date::Parse;
$time = str2time($date);
($ss,$mm,$hh,$day,$month,$year,$zone) = strptime($date);
DESCRIPTION
"Date::Parse" provides two routines for parsing date strings into time
values.
str2time(DATE [, ZONE])
"str2time" parses "DATE" and returns a unix time value, or undef
upon failure. "ZONE", if given, specifies the timezone to assume
when parsing if the date string does not specify a timezone.
strptime(DATE [, ZONE])
"strptime" takes the same arguments as str2time but returns an
array of values "($ss,$mm,$hh,$day,$month,$year,$zone,$century)".
Elements are only defined if they could be extracted from the date
string. The $zone element is the timezone offset in seconds from
GMT. An empty array is returned upon failure.
MULTI-LANGUAGE SUPPORT
Date::Parse is capable of parsing dates in several languages, these
include English, French, German and Italian.
$lang = Date::Language->new('German');
$lang->str2time("25 Jun 1996 21:09:55 +0100");
EXAMPLE DATES
Below is a sample list of dates that are known to be parsable with
Date::Parse
1995:01:24T09:08:17.1823213 ISO-8601
1995-01-24T09:08:17.1823213
Wed, 16 Jun 94 07:29:35 CST Comma and day name are optional
Thu, 13 Oct 94 10:13:13 -0700
Wed, 9 Nov 1994 09:50:32 -0500 (EST) Text in ()'s will be ignored.
21 dec 17:05 Will be parsed in the current time zone
21-dec 17:05
21/dec 17:05
21/dec/93 17:05
1999 10:02:18 "GMT"
16 Nov 94 22:28:20 PST
LIMITATION
Date::Parse uses Time::Local internally, so is limited to only parsing
dates which result in valid values for Time::Local::timelocal. This
generally means dates between 1901-12-17 00:00:00 GMT and 2038-01-16
23:59:59 GMT
BUGS
When both the month and the date are specified in the date as numbers
they are always parsed assuming that the month number comes before the
date. This is the usual format used in American dates.
The reason why it is like this and not dynamic is that it must be
deterministic. Several people have suggested using the current locale,
but this will not work as the date being parsed may not be in the
format of the current locale.
My plans to address this, which will be in a future release, is to
allow the programmer to state what order they want these values parsed
in.
