=head1 NAME

DateTime::Format::Epoch::ActiveDirectory -  Active Directory epoch seconds

=head1 SYNOPSIS

  use DateTime::Format::Epoch::ActiveDirectory;

  my $dt = DateTime::Format::Epoch::ActiveDirectory
                ->parse_datetime( 1051488000 );

  DateTime::Format::Epoch::ActiveDirectory->format_datetime($dt);
   # 1051488000

  my $formatter = DateTime::Format::Epoch::ActiveDirectory->new();
  my $dt2 = $formatter->parse_datetime( 1051488000 );
  $formatter->format_datetime($dt2);

=head1 DESCRIPTION

This module can convert a DateTime object (or any object that can be
converted to a DateTime object) to the number of seconds since the
epoch used in Microsoft Active Directory.

Note that this epoch is defined in the I<local> time zone. This means
that these two pieces of code will print the same number of seconds,
even though they represent two datetimes 6 hours apart:

    $dt = DateTime->new( year => 2003, month => 5, day => 2,
                         time_zone => 'Europe/Amsterdam' );
    print $formatter->format_datetime($dt);

    $dt = DateTime->new( year => 2003, month => 5, day => 2,
                         time_zone => 'America/Chicago' );
    print $formatter->format_datetime($dt);

=head1 METHODS

Most of the methods are the same as those in L<DateTime::Format::Epoch>.
The only difference is the constructor.
