[time-nuts] Lucent GPS UTC confusion

Thanks to Paul, the Lucent is now reporting UTC. Apparently, even
though the Status screen says UTC, it doesn't really change until
after a power cycle. Bad UI.

My Z3801A is off at the moment and about to go onto the bench, so I
compared against: http://time.is/UTC
