# update_leap_seconds

astropy.time.update_leap_seconds(files=None)

  If the current ERFA leap second table is out of date, try to update it.

  Uses `astropy.utils.iers.LeapSeconds.auto_open` to try to find an up-to-date table. See that routine for the definition of “out of date”.

  In order to make it safe to call this any time, all exceptions are turned into warnings,

  Parameters:
    files `python:list` of python:path-like object, optional

      List of files/URLs to attempt to open. By default, uses defined by `astropy.utils.iers.LeapSeconds.auto_open`, which includes the table used by ERFA itself, so if that is up to date, nothing will happen.

  Returns:
    n_update `python:int`

      Number of items updated.
