Isn't there an extra extra second there? The UT+ is showing two :60s; shouldn't there be only one? Another thing I haven't dug into, but if the GPS is outputting the time at the *next* PPS signal, the sentence will appear to be ahead compared to a display that's attempting to show the *current* time. Not sure if that's the case with TAC32. [ snip ] > I obtained my data using a Nikon D70 digital still camera > operated in 'burst' mode taking about three frames per second > of the computer screen.

I had my D70 in burst mode pointed at the Spectracom 8170 and HP5065A clocks; unfortunately, the 8170 took 4 minutes to update, so I didn't capture the transition. I did get a couple of shots after the change showing the 1 second disparity between the two, but it's just not the same as capturing 23:59:60 (which, alas, the Spectracom never did display -- it sent :59:59 twice).
