I wouldn't take that bet. I know Mac OS X can measure time as finely
as nanoseconds (but I have no idea how many services, i.e. sockets,
actually work at nanosecond resolutions; it doesn't seem outside the
realm of possibility that, given the way technologies advance, that
within a few short years, microseconds simply won't be fine enough.
One of the nice things about double-as-time-unit is that it avoids
resolution issues altogether.
