NAME

       DateTime::LeapSecond - leap seconds table and utilities

VERSION

       version 0.75

SYNOPSIS

	 use DateTime;
	 use DateTime::LeapSecond;

	 print "Leap seconds between years 1990 and 2000 are ";
	 print DateTime::Leapsecond::leap_seconds( $utc_rd_2000 ) -
	       DateTime::Leapsecond::leap_seconds( $utc_rd_1990 );

DESCRIPTION

       This module is used to calculate leap seconds for a given Rata Die day. It is used when DateTime.pm cannot compile the XS version of this
       code.

       This library is known to be accurate for dates until December 2009.

       There are no leap seconds before 1972, because that's the year this system was implemented.

       o   leap_seconds( $rd )

	   Returns the number of accumulated leap seconds for a given day, in the range 0 .. 22.

       o   extra_seconds( $rd )

	   Returns the number of leap seconds for a given day, in the range -2 .. 2.

       o   day_length( $rd )

	   Returns the number of seconds for a given day, in the range 86398 .. 86402.

NAME

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

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);

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 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);

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.
