DESCRIPTION

17       This module is used to calculate leap seconds for a given Rata Die day.
18       It is used when DateTime.pm cannot compile the XS version of this code.
19
20       This library is known to be accurate for dates until December 2009.
21
22       There are no leap seconds before 1972, because that's the year this
23       system was implemented.
