I think the only reason for initializing to the system UTC (as most
drivers do) is historical.  The first Intel driver was simply copied.
I've been thinking recently that we should standardize this.  I'm open
for suggestions on how to do this. Remember that the system time is
likely wrong at driver initialization time.

Thanks,
Richard
