Python Leap Second List

Leap seconds are corrections applied irregularly so that the UTC day stays fixed to the earth's rotation.

This module provides a class for parsing and validating the standard leap-seconds.list file. Once parsed, it is possible to retrieve the full list of leap seconds, or find the TAI-UTC offset for any UTC time.
