use clock_gettime for time resolution

This lets us use CLOCK_MONOTONIC so we are not affected by
system clock changes.

We still convert to microseconds instead of nanoseconds for
(pure)-Ruby 1.8 code compatibility.  There is also little need
for nanosecond timer resolution in log files (microsecond is not
needed, even).
