use DateTime;
use DateTime::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 DateTime.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.
