SUBROUTINE USER_CLOCK(PELAPSED_TIME,PELAPSED_TIME_SINCE,PVECTOR_CP,PTOTAL_CP)

!**** *USER_CLOCK* - interface to system dependent timer routines

!     Purpose.
!     --------
!        Returns elapsed and CP from the start of execution.
!        Elapsed time is made relative to the first call to USER_CLOCK.

!**   Interface.
!     ----------
!        ZTIME=USER_CLOCK(PELAPSED_TIME,PELAPSED_TIME_SINCE,
!                         PVECTOR_CP,PTOTAL_CP)

!        Explicit arguments: (All are optional arguments)
!                           PELAPSED_TIME=wall clock time (seconds)
!                           PELAPSED_TIME_SINCE=wall clock time (seconds)
!                             change from input value of this parameter
!                           PVECTOR_CP=CP vector time  (seconds)
!                           PTOTAL_CP=total CP time   (seconds)
