DateTime::Format::Epoch::MacOS(3pm)			User Contributed Perl Documentation		       DateTime::Format::Epoch::MacOS(3pm)

NAME
DateTime::Format::Epoch::MacOS - Convert DateTimes to/from Mac OS epoch seconds 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 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 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. METHODS
Most of the methods are the same as those in DateTime::Format::Epoch. The only difference is the constructor. o new() Constructor of the formatter/parser object. It has no parameters. SUPPORT
Support for this module is provided via the datetime@perl.org email list. See http://lists.perl.org/ for more details. AUTHOR
