# UseBy

The number of seconds for which to treat a license as active, after the last time it was issued or updated. After this amount of time, if the license has not been updated, License Server considers the license to be stale, and the RevokeStaleLicenses action will revoke the license.

You can set `UseBy` to a negative value to revoke all licenses.
