12 use Email::Date;
13
14 my $email = join '', <>;
15 my $date = find_date($email);
16 print $date->ymd;
17
18 my $header = format_date($date->epoch);

20 Email::Simple->create(
21 header => [
22 Date => $header,
23 ],
24 body => '...',
25 );

28 Achtung! Probably you'll be find just using Email::Date::Format to
29 produce dates or Date::Parse to parse dates. This module isn't much
30 needed anymore, but does provide "find_date", described below.
31
32 RFC 2822 defines the "Date:" header. It declares the header a required
33 part of an email message. The syntax for date headers is clearly laid
34 out. Stil, even a perfectly planned world has storms. The truth is,
35 many programs get it wrong. Very wrong. Or, they don't include a
36 "Date:" header at all. This often forces you to look elsewhere for the
37 date, and hoping to find something.
38
39 For this reason, the tedious process of looking for a valid date has
40 been encapsulated in this software. Further, the process of creating
41 RFC compliant date strings is also found in this software.
42
44 find_date
45 my $time_piece = find_date $email;
46
47 "find_date" accepts an email message in any format Email::Abstract can
48 understand. It looks through the email message and finds a date,
49 converting it to a Time::Piece object.
50
51 If it can't find a date, it returns false.
52
53 "find_date" is exported by default.
54
55 format_date
56 my $date = format_date; # now
57 my $date = format_date( time - 60*60 ); # one hour ago
58
59 "format_date" accepts an epoch value, such as the one returned by
60 "time". It returns a string representing the date and time of the
61 input, as specified in RFC 2822. If no input value is provided, the
62 current value of "time" is used.
63
64 "format_date" is exported by default.
65
66 format_gmdate
67 my $date = format_gmdate;
68
69 "format_gmdate" is identical to "format_date", but it will return a
70 string indicating the time in Greenwich Mean Time, rather than local
71 time.
72
73 "format_gmdate" is exported on demand, but not by default.
