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.
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.
