Email::Date - Find and Format Date Headers
my $email = join '', <>;
my $date = find_date($email);
my $header = format_date($date->epoch);
header => [
Date => $header,
body => '...',
Probably you'll be find just using Email::Date::Format to
produce dates or Date::Parse to parse dates. This module isn't much needed
anymore, but does provide "find_date", described below.
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
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;
"find_date" accepts an email message in any format Email::Abstract can
understand. It looks through the email message and finds a date, converting it
to a Time::Piece object.
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
"format_gmdate" is exported on demand, but not by default.
