1 – 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.
