Command:   readclock - read the real time clock [IBM PC/AT and AMIGA]
Syntax:    readclock
Flags:     (none)
Example:   date `/usr/bin/readclock` </dev/tty # Useful in /etc/rc

     Readclock reads the AT's real time clock and prints the result in a
form  useful  to date, namely, MMDDYYhhmmss. If the clock does not exist
(e.g., on a PC), it outputs '-q' to query the user  for  the  time.  The
example given above can be put in /etc/rc to load the real time when the
system is booted.
