I just pushed a commit (e253862f) to remove automatically updating the legacy time stamps to true unique identifiers. It was obvious that this was causing more confusion than the potential for clashes between shared schematics. If there wasn’t an issue with the time stamp identifiers than converting them to true unique identifiers wouldn’t solve anything. You no longer need to update your board footprint symbol link as they will not be changed. If you already did this, there is no need to make any changes.
