B:
There is a utility named TimeThis.exe that will run under Windows
NT/2000/XP and I presume 2000 Server and 2003 Server. It works
for most any .EXE including Fortran .EXE's. Download it at:
http://www.microsoft.com/windows2000/techinfo/reskit/tools/existing/timethis-o.asp
As you mention, you can get wall clock time via a .BAT file like:
echo off
rem Set the prompt to the time of day.
prompt $t$g
if exist %1.BAT GOTO CALLIT
echo on
%1 %2 %3 %4 %5 %6 %7 %8 %9
echo off
GOTO WRAPUP
:CALLIT
echo on
CALL %1 %2 %3 %4 %5 %6 %7 %8 %9
echo off
:WRAPUP
rem Restore the usual prompt.
prompt $p$g
