=head1 NAME
Email::Date - Find and Format Date Headers
=head1 VERSION
version 1.104
=head1 SYNOPSIS
use Email::Date;
my $email = join '', <>;
my $date = find_date($email);
print $date->ymd;
my $header = format_date($date->epoch);
Email::Simple->create(
header => [
Date => $header,
],
body => '...',
);
=head1 DESCRIPTION
B<Achtung!> Probably you'll be find just using L<Email::Date::Format> to
produce dates or L<Date::Parse> to parse dates. This module isn't much needed
anymore, but does provide C<find_date>, described below.
RFC 2822 defines the C<Date:> header. It declares the header a required
part of an email message. The syntax for date headers is clearly laid
out. Stil, even a perfectly planned world has storms. The truth is, many
programs get it wrong. Very wrong. Or, they don't include a C<Date:> header
at all. This often forces you to look elsewhere for the date, and hoping
to find something.
For this reason, the tedious process of looking for a valid date has been
encapsulated in this software. Further, the process of creating RFC
compliant date strings is also found in this software.
=head1 FUNCTIONS
=head2 find_date
my $time_piece = find_date $email;
C<find_date> accepts an email message in any format
L<Email::Abstract|Email::Abstract> can understand. It looks through the email
message and finds a date, converting it to a L<Time::Piece|Time::Piece> object.
If it can't find a date, it returns false.
C<find_date> is exported by default.
=head2 format_date
my $date = format_date; # now
my $date = format_date( time - 60*60 ); # one hour ago
C<format_date> accepts an epoch value, such as the one returned by C<time>.
It returns a string representing the date and time of the input, as
specified in RFC 2822. If no input value is provided, the current value
of C<time> is used.
C<format_date> is exported by default.
=head2 format_gmdate
my $date = format_gmdate;
C<format_gmdate> is identical to C<format_date>, but it will return a string
indicating the time in Greenwich Mean Time, rather than local time.
C<format_gmdate> is exported on demand, but not by default.
