The clock was supported to a degree under Basic by Disto/CRC in their
CDOS ROM.   There was a CLOCK ON  command that would continuously
display the time in the corner of the screen by means of a patch to
the 60 Hz IRQ service routine.

I had support for the 2 types of Disto clocks and the
SmartWatch/Burke&Burke clock in Extended ADOS-3, which used the clock
for date-stamping files (date and time were displayed by the DIR
command), printing the date/time at the top of printed program
listings, and a DATE$ function usable in Basic programs.
