Actually, the GPS (satellite) time is off by about 12 seconds. Each manufacturer corrects for this inside the unit. Accuracy may be affected by internal errors, but I'm sure it's accurate enough for celestial navigation.

I have a few basic questions. First, any strong feelings out there about the Starpath workforms? I like them a lot, I use them with pub229, and they seem quite a bit more efficient than Navy-type strip forms. I haven't tried then with NAO method yet. Second, is volume 1 of 249 only used for star identificaton, or can it be used for reductions as well? All we tend to use it for in the Coast Guard is as a star finder. I reduced a star sight using only pub249 and it seemed to work, although I'm confused by the fact that it doen't include any declination values? Third, I've been using DGPS as my time tick for all my sights, (we don't have a chronometer). Is this as accurate as I think it is? Lastly, I'm intrigued by what I've heard about 211/Ageton sight reduction. Where can I find out more and/or get a copy of the requisite tables/forms/instructions.
