leapseconddata 4.1.1

Use the list of known and scheduled leap seconds

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.
