DESCRIPTION

20       This module is used to calculate leap seconds for a given Rata Die day.
21       It is used when DateTime.pm cannot compile the XS version of this code.
22
23       This library is known to be accurate for dates until Jun 2017.
24
25       There are no leap seconds before 1972, because that's the year this
26       system was implemented.
