I am both a heavy MacOS user and Linux user.

I consider MacOS more "unix-like' than Linux because (1) the Darwin core and (2) UNIX certification.

The fact of the matter is that UNIX and unix developers are responsible for the success of both MacOS and Linux and it is pointless to debate.

In my view, if unix had not of been tied up in years of litigation based on commercial (profit motivated) licenses and copyrights and unix had gone the same route as Linux, unix would be the dominate force in computing today.

Yes, MacOS is based on Unix, pure and simple.

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
