Getting back to the original question, I noticed no out-of-the ordinary
change in the offset of the observatory's hydrogen maser to GPS. Attached is
a graph. Note the GPS is an old TAC and plotted are five minute averages of
ten second samples. The y axis is in microseconds and the x axis is days
Hi, just found a handy free iPhone app called Emerald Time. It uses
ntp and visually shows the time to within 100 msec. I've videod the
screen and compared it with a real clock and found the claim to be

clock we'd actually have something. By using Emerald Time my i-phone's internal
clock has shown itself to be off by as much as 12.4 seconds. That no longer
qualifies as a usable clock to me. If I am out somewhere and
