SETCLOCK LOAD|SAVE

* SETCLOCK only works if you have a battery backed up clock (BBUC).
  It accesses the adresses $DC0000 and I do not know if it works
  with very old or very new (A1200) clocks.
* SETCLOCK LOAD sets the systemtime (you can see the systemtime with
   DATE  or  MEMCLK ) to the time in the BBUC (hopefully this is the
  right time).
* SETCLOCK SAVE first resets the BBUC, then stores the systemtime
  to the BBUC.
  To set the BBUC to the right time, use  DATE  to set the correct
  date and time, then use SETCLOCK SAVE.

eg.     setclock load
        setclock save
