+
+Email::Date::Format - produce RFC 2822 date strings
+
+=head1 SYNOPSIS
+
+  use Email::Date::Format qw(email_date);
+  
+  my $header = email_date($date->epoch);
+  
+  Email::Simple->create(
+    header => [
+      Date => $header,
+    ],
+    body => '...',
+  );
+
+=head1 DESCRIPTION
+
+This module provides a simple means for generating an RFC 2822 compliant
+datetime string.  (In case you care, they're not RFC 822 dates, because they
+use a four digit year, which is not allowed in RFC 822.)

+
+=item email_date
+
+  my $date = email_date; # now
+  my $date = email_date( time - 60*60 ); # one hour ago
+
+C<email_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 only if requested.
+
+=item email_gmdate
+
+  my $date = email_gmdate;
+
+C<email_gmdate> is identical to C<email_date>, but it will return a string
+indicating the time in Greenwich Mean Time, rather than local time.
+
+C<format_gmdate> is exported only if requested.
