	  struct timespec *tp );

DESCRIPTION

  The getclock() function sets the current value of the clock specified by
  clktyp into the location pointed to by the tp parameter.

  The clktyp parameter is given as a symbolic constant name, as defined in

  supported.

  For the clock specified by TIMEOFDAY, the value returned by this function
  is the elapsed time since the epoch. The epoch is referenced to 00:00:00
