Short Break Check	Clockings that create Short Breaks are being tested for removal. The clocking times are in ToiletOut and ToiletIn. If you set ScriptShortBreak to 1 then the clockings will be removed. If  ToiletIn - ToiletOut is less than, or equal to ShortBreak then the clockings will be removed.
Check Unexpected clockings	An unexpected pair of clockings has been detected. The clocking times are stored in ClockIn and ClockOut. ClockFirst is set to I if the pair is In/Out and set to O if the pair is Out/In. You cannot change anything here, but you can use the Registers to store information for acting on elsewhere in the script.
