This is from the 5.5 Reference Manual Laserrom:
SETCLOCK

Alters the system time or system time zone.
SYNTAX


         {DATE= date spec; TIME= time spec [;GRADUAL]}
         {                                 [;NOW    ]}
SETCLOCK {                                           }
         {CORRECTION= correction spec                }
         {TIMEZONE= time zone spec                   }
         {;CANCEL                                    }

We're on 5.0 and happily use this command when it's time for
'daylight-saving' adjustments (plus a couple of times/month since our
hardware-clock is a bit fast :-). The *big* change in 5.0 (and later) is
that you don't have reboot the machine in order to change the time. For more
details try :HELP SETCLOCK ALL
