NAME

6       Date::Parse - Parse date strings into time values
7

SYNOPSIS

9               use Date::Parse;
10
11               $time = str2time($date);
12
13               ($ss,$mm,$hh,$day,$month,$year,$zone) = strptime($date);
14

DESCRIPTION

16       "Date::Parse" provides two routines for parsing date strings into time
17       values.
18
19       str2time(DATE [, ZONE])
20           "str2time" parses "DATE" and returns a unix time value, or undef
21           upon failure.  "ZONE", if given, specifies the timezone to assume
22           when parsing if the date string does not specify a timezone.
23
24       strptime(DATE [, ZONE])
25           "strptime" takes the same arguments as str2time but returns an
26           array of values "($ss,$mm,$hh,$day,$month,$year,$zone,$century)".
27           Elements are only defined if they could be extracted from the date
28           string. The $zone element is the timezone offset in seconds from
29           GMT. An empty array is returned upon failure.
30

MULTI-LANGUAGE SUPPORT

32       Date::Parse is capable of parsing dates in several languages, these
33       include English, French, German and Italian.
34
35               $lang = Date::Language->new('German');
36               $lang->str2time("25 Jun 1996 21:09:55 +0100");

46        Wed, 9 Nov 1994 09:50:32 -0500 (EST)  Text in ()'s will be ignored.
47        21 dec 17:05                          Will be parsed in the current time zone
48        21-dec 17:05
49        21/dec 17:05
50        21/dec/93 17:05

LIMITATION

55       Date::Parse uses Time::Local internally, so is limited to only parsing
56       dates which result in valid values for Time::Local::timelocal. This
57       generally means dates between 1901-12-17 00:00:00 GMT and 2038-01-16
58       23:59:59 GMT

BUGS

61       When both the month and the date are specified in the date as numbers
62       they are always parsed assuming that the month number comes before the
63       date. This is the usual format used in American dates.
64
65       The reason why it is like this and not dynamic is that it must be
66       deterministic. Several people have suggested using the current locale,
67       but this will not work as the date being parsed may not be in the
68       format of the current locale.
69
70       My plans to address this, which will be in a future release, is to
71       allow the programmer to state what order they want these values parsed
72       in.
