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

14 Date parsing can also use options. The options are as follows:
15 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.

33 Absolute date formats
34 Dow, dd Mon yy
35 Dow, dd Mon yyyy
36 Dow, dd Mon
37 dd Mon yy
38 dd Mon yyyy
39 Month day{st,nd,rd,th}, year
40 Month day{st,nd,rd,th}
41 Mon dd yyyy
42 yyyy/mm/dd
43 yyyy-mm-dd (usually the best date specification syntax)
44 yyyy/mm
45 mm/dd/yy
46 mm/dd/yyyy
47 mm/yy
48 yy/mm (only if year > 12, or > 31 if UK)
49 yy/mm/dd (only if year > 12 and day < 32, or year > 31 if UK)
50 dd/mm/yy (only if UK, or an invalid mm/dd/yy or yy/mm/dd)
51 dd/mm/yyyy (only if UK, or an invalid mm/dd/yyyy)
52 dd/mm (only if UK, or an invalid mm/dd)
53 Relative date formats:
55 count "days"
56 count "weeks"
57 count "months"
58 count "years"
59 Dow "after next"
60 Dow "before last"
61 Dow (requires PREFER_PAST or PREFER_FUTURE)
62 "next" Dow
63 "tomorrow"
64 "today"
65 "yesterday"
66 "last" dow
67 "last week"
68 "now"
69 "now" "+" count units
70 "now" "-" count units
71 "+" count units
72 "-" count units
73 count units "ago"
74 Absolute time formats:
76 hh:mm:ss[.ddd]
77 hh:mm
78 hh:mm[AP]M
79 hh[AP]M
80 hhmmss[[AP]M]
81 "noon"
82 "midnight"
83 Relative time formats:
85 count "minutes" (count can be franctional "1.5" or "1 1/2")
86 count "seconds"
87 count "hours"
88 "+" count units
89 "+" count
90 "-" count units
91 "-" count
92 count units "ago"
93 Timezone formats:
95 [+-]dddd
96 GMT[+-]d+
97 [+-]dddd (TZN)
98 TZN
99 Special formats:
101 [ d]d/Mon/yyyy:hh:mm:ss [[+-]dddd]
102 yy/mm/dd.hh:mm

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 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 If a timezone is specified it must be after the time. Year
113 specifications can be tacked onto the end of absolute times.
114 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.

128 $seconds = parsedate("last Tuesday");
129 $seconds = parsedate("Sunday before last");
130 ($seconds, $remaining) = parsedate("today is the day");
132 ($seconds, $error) = parsedate("today is", WHOLE=>1);
