You don't say what you're executing, but doing `/bin/time -v ls -l /bin' I get:
        Command being timed: "ls -l /bin"
        User time (seconds): 0.45
        System time (seconds): 0.29

So it appears to be you're setup.  I'm using NT4sp4, Cygwin-1.1.4.  The output
of `cygcheck -s -r -v' pasted in a mail and sent to the list might be useful.

Cheers,
