Same here, it's day "597" according to my Datum 9390 Rb clock.  The time
appears correct.  Also interesting is the 10 MHz output, which appears to be
about 2E-10 high compared to a Thunderbolt and cesium standard.  That wasn't
the case when I first bought the 9390 a year or so ago, but it's been true
for at least a couple of days now.  There's no indication in the display
that the rubidium's unlocked, as the status remains "Doing GPS correction
(System check OK)".

Anyone else seeing a constant frequency error from theirs?
