Extension scrubber time: In previous version only one scrubber timer was available. After movement of scruvver timer menu menu space became available allowing to upgrade the functionality to support two scrubbers. To make it easier to identify combination ID to used scrubber the date of the last usage of the scrubber timer has been added.
