add util.log_time helper

The reason for this is that more and more things I was wanting to be able to
see how long they took. This puts that time logic into a single place. It
also supports from /proc/uptime as the timing mechanism.

While reading /proc/uptime is almost certainly slower than time.time(), it does
give millisecond granularity and is not affected by 'ntpdate' having run in
between the two events.
