DateTime::LeapSecond(3)

NAME
DateTime::LeapSecond - leap seconds table and utilities

VERSION
version 1.26

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.

•   leap_seconds( $rd )

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

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

•   day_length( $rd )

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