But in fact they are correct.  The SetClock command (found in the c: dir-
ectory) has been added to the Startup-Sequence to set the Amiga's system
time from that in the battery backed-up clock.  The SetClock command can
also be used to save the system time to the bbc.  Usage is as follows:

		setclock opt load|save
		    opt load   loads system time/date from clock
		    opt save   saves system time/date to clock
