# update_leap_seconds¶

astropy.time.update_leap_seconds(files=None)[source]

If the current ERFA leap second table is out of date, try to update it.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 See that routine for the definition of “out of date”.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
fileslist of path, 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_updateint

Number of items updated.
