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If the current ERFA leap second table is out of date, try to update it.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 See that routine for the definition of “out of date”.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

Number of items updated.
