rtc —
clock0 at mainbus0
rtc driver supports reading from and writing to the
  Atari real time clock (RTC). When reading from the RTC, the format string of
  the output, as described in the
  strftime(3) manual page,
  is:
``%Y%m%d%H%M.%S''
The same format is used to set the RTC to the current date. Note that the kernel expects the RTC to run in UTC.
