Arguments

 

time1

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

   First time, from which LIB$SUB_TIMES subtracts the second
   time. The time1 argument is the address of an unsigned quadword
   containing this time. The time1 argument must represent a later
   or equal time or a longer or equal time interval than time2. The
   time1 argument may be either absolute time or delta time as long
   as time2 is of the same type. If time1 and time2 are of different
   types, time1 must be the absolute time.
 

time2

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

   Second time, which LIB$SUB_TIMES subtracts from the first time.
   The time2 argument is the address of an unsigned quadword
   containing this time. The time2 argument must represent an
   earlier or equal time or a shorter or equal time interval than
   time1. The time2 argument may be either absolute time or delta
   time as long as time1 is of the same type. If time2 and time1 are
   of different types, time2 must be the delta time.
 

resultant-time

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

   The result of subtracting time2 from time1. The resultant-time
   argument is the address of an unsigned quadword containing the
   result. If both time1 and time2 are delta times, then resultant-
   time is a delta time. If both time1 and time2 are absolute times,
   then resultant-time is a delta time. If time1 is an absolute time
   and time2 is a delta time, then resultant-time is an absolute
   time.
