[time-nuts] Lucent GPS UTC confusion

I noticed on the Status screen that the Lucent unit said the PPS was
locked to GPS, not UTC, as the Z3801A is. So, I issued ":DIAG:GPS:UTC
1" and "TST?" to correct this.

But things are not as I expected. Displaying the clock for both
GPSDO's in Z38xx now shows them to be 17 seconds different, which is
of course the leap seconds.

This seems backwards. With both units set to UTC, why are they showing
different times?
