NAME ^

DateTimeX::Lite::LeapSecond - leap seconds table and utilities

SYNOPSIS ^

  use DateTimeX::Lite;
  use DateTimeX::Lite::LeapSecond;

  print "Leap seconds between years 1990 and 2000 are ";
  print Date::Leapsecond::leap_seconds( $utc_rd_2000 ) -
        Date::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 DateTimeX::Lite.pm cannot compile the XS version of this code.

This library is known to be accurate for dates until december 2005.

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