# 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
```

Use the list of known and scheduled leap seconds.
