Email::Date - Find and Format Date Headers
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 => '...', );
RFC 2822 defines the
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
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.
my $time_piece = find_date $email;
If it can't find a date, it returns false.
find_date is exported by default.
my $date = format_date; # now my $date = format_date( time - 60*60 ); # one hour ago
format_date accepts an epoch value, such as the one returned by
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
time is used.
format_date is exported by default.
my $date = format_gmdate;
format_gmdate is identical to
format_date, but it will return a string indicating the time in Greenwich Mean Time, rather than local time.
format_gmdate is exported on demand, but not by default.
