# 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.

# `leapsecond` program

Access leap second data from the command line.

```

Usage: leapsecond [OPTIONS] COMMAND [ARGS]...

  Access leap second database information

Options:

  --url TEXT            URL for leap second data (unspecified to use default

                        source)

  --debug / --no-debug

  --help                Show this message and exit.

Commands:

  convert              Convert timestamps between TAI and UTC

  info                 Show information about leap second database

  next-leapsecond      Get the next leap second after a given UTC timestamp

  offset               Get the UTC offset for a given moment, in seconds

  previous-leapsecond  Get the last leap second before a given UTC timestamp

  table                Print information about leap seconds
