Jeff Epler 8007b02dcc Add more TAI-wrangling 
* leapseconddata.tai is a timezone object.  BEWARE, because of reasons,
   it compares equal to datetime.datetime.utc!

 * tai_offset can take either kind of timestamp

 * to_tai, tai_to_utc: convert to/from the TAI timescale.

 * is_leap_second: return True if the given second is a leap second.
   In the UTC timescale, the ":59" second returns True even though
   "only" the second repetition of :59 is a leap second

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.
