=head1 NAME

DateTime::Format::Epoch::MacOS - Convert DateTimes to/from Mac OS epoch seconds

=head1 SYNOPSIS

  use DateTime::Format::Epoch::MacOS;

  my $dt = DateTime::Format::Epoch::MacOS->parse_datetime( 1051488000 );
  DateTime::Format::Epoch::MacOS->format_datetime($dt);
   # 1051488000

  my $formatter = DateTime::Format::Epoch::MacOS->new();

  my $dt2 = $formatter->parse_datetime( 1051488000 );

  $formatter->format_datetime($dt2);
   # 1051488000

=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 Mac OS
epoch.

Note that the Mac OS 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);

Mac OS X is a Unix system, and uses the Unix epoch
(1970-01-01T00:00:00). Use DateTime::Format::Epoch::Unix instead.

=head1 METHODS

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