FWIW, I've often used timetimes to try to narrow down where
time is spent. Sometimes, global performance measurements
such as hot spots, etc, can be a little skewed with code
that we didn't want to analyze. Or I've also worked on platforms
where performance analysis tools are not available. So I used
the poor man's performance tool, timestamped traces.
