Arguments

 

number-of-days

   OpenVMS usage:longword_signed
   type:         longword integer (signed)
   access:       write only
   mechanism:    by reference

   Number of days since the system zero date. The number-of-days
   argument is the address of a signed longword integer containing
   the day number.
 

user-time

   OpenVMS usage:date_time
   type:         quadword (unsigned)
   access:       read only
   mechanism:    by reference

   User-supplied time, in 100-nanosecond units. The user-time
   argument is the address of a signed quadword integer containing
   the user time. A positive value indicates an absolute time, while
   a negative value indicates a delta time. This is an optional
   argument. If user-time is omitted, the default is the current
   system time. This quadword time value is obtained by calling the
   $BINTIM system service.

   If time is passed as zero by value, the numeric value for
   the current day is returned. If time is passed as a zero by
   reference, the number returned represents the day of November
   17, 1858, rather than the current day.
 

day-time

   OpenVMS usage:longword_signed
   type:         longword integer (signed)
   access:       write only
   mechanism:    by reference

   Number of 10-millisecond units since midnight of the user-time
   argument. The day-time argument is the address of a signed
   longword integer into which LIB$DAY writes this number of units.
