Implementation of Fortran SECOND intrinsic function.
This file is part of the Fortran-to-Java (f2j) system,
developed at the University of Tennessee.
This class implements the Fortran 77 SECOND intrinsic.
SECOND is supposed to provide the CPU time for the
process since the start of execution. Currently,
Java doesn't have a similar method, so we use this
cheesy simulation:
- f2j inserts a call at the beginning of the program
to record the start time.
- on the first call, record the current time.
- on subsequent calls, return the difference
between the current call time and the starting
time.
Essentially, this version of etime returns the
wall-clock time elapsed since the beginning of
execution.
