Argument

 

timadr

   OpenVMS usage:date_time
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by 32- or 64-bit reference (Alpha and Integrity
                 servers)
   New absolute time value for the system time, specifying the
   number of 100-nanosecond intervals since 00:00 o'clock, November
   17, 1858. The timadr argument is the 32- or 64-bit address (on
   Alpha and Integrity server systems) of a quadword containing the
   new system time value. A negative (delta) time value is invalid.

   If you do not specify the value of timadr or specify it as 0,
   $SETIME recalibrates the system time using the time-of-year
   clock.
