On Linux, for running programs batch-style, I use a bash script
which essentially runs the following commands:

nice time -f "$progname: Elapsed: %E; System: %S; User: %U; Major PFs: %F"\
        stata $arg2 -b do $statacode 2> /tmp/stb$$timelog
    cat /tmp/stb$$timelog >> ${statacode}.log
    echo "$progname: Finished: `date`" >> ${statacode}.log

This appends a block like this:

stb: Elapsed: 7:45.04; System: 0.87; User: 434.70; Major PFs: 29
stb: Finished: Tue Apr 17 23:14:33 IST 2007

at the end of the log. 

Perhaps not what you had in mind (timing individual commands
interactively?) but I find it very useful to have this info by
default. Also, jobs that take long enough for it to matter are well
worth doing batch-wise anyway.
