SYNOPSIS

use Date::Leapsecond;
use Time::Local;  

$epoch_2000 = timegm(0,0,0,1,0,2000 - 1900);
$epoch_1990 = timegm(0,0,0,1,0,1990 - 1900);
print "Seconds between years 1990 and 2000 are ";
print Date::Leapsecond::ut1($epoch_2000) - 
      Date::Leapsecond::ut1($epoch_1990); 
print " instead of ";
print $epoch_2000 - 
      $epoch_1990;
