New Revision: 187580
URL: http://svn.freebsd.org/changeset/base/187580
Log:
- Update my copyright.
- Print human readable time as a float with two digits of precision. Use
ns now as well since clock periods are well into the hundreds of
picoseconds now.
- Show the average duration in the stats frame. This is often more useful
than total duration.
