      NAME
           etime, dtime - return elapsed execution time

      SYNTAX
           function etime (tarray)
           real tarray(2)

           function dtime (tarray)
           real tarray(2)

      DESCRIPTION
           Etime returns in tarray(1) the elapsed user time for the
           calling process since start of execution, and in tarray(2)
           the elapsed system time for the calling process since start
           of execution.

           Dtime returns in tarray(1) the delta time for the calling
           process since the last call to dtime, and in tarray(2) the
           delta system time for the calling process since the last
           call to dtime.

           The return value of dtime and etime is the sum of the two
           tarray times they report.

           The resolution of all timing is one millisecond.

      BUGS
           The f77 compiler fails to convert the returned value to
           single precision from double precision, so the return value
           must be read as a double.
