NAME

Email::Date - Find and Format Date Headers

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 => '...',
   );

DESCRIPTION

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.

FUNCTIONS

find_date
   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.

format_date
   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.

format_gmdate
   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.
