1SUBROUTINE USER_CLOCK(PELAPSED_TIME,PELAPSED_TIME_SINCE,PVECTOR_CP,PTOTAL_CP)
2
3!**** *USER_CLOCK* - interface to system dependent timer routines
4
5!     Purpose.
6!     --------
7!        Returns elapsed and CP from the start of execution.
8!        Elapsed time is made relative to the first call to USER_CLOCK.

10!**   Interface.
11!     ----------
12!        ZTIME=USER_CLOCK(PELAPSED_TIME,PELAPSED_TIME_SINCE,
13!                         PVECTOR_CP,PTOTAL_CP)
14
15!        Explicit arguments: (All are optional arguments)
16!                           PELAPSED_TIME=wall clock time (seconds)
17!                           PELAPSED_TIME_SINCE=wall clock time (seconds)
18!                             change from input value of this parameter
19!                           PVECTOR_CP=CP vector time  (seconds)
20!                           PTOTAL_CP=total CP time   (seconds)
