/* 
	This program reads the WWV clock and corrects the system clock
	based on the WWV clock.  It will wake up once an hour in order
	to check the clock.  If the clock has lost sync, it aborts.

	Planned improvement:  if timesync has been lost, it will call
	the NIST or Nautical Observatory phone line to check the time.

	1999_11_22  Eliminated CTS10 related code to transport to Linux.
