The GPS downloads the Zulu time with every transmission. The only delay would be decoding the actual transmission.
In fact, GPS can report any time. We use UTC. Parsing the data is trivial and we do it all the time. Both NMEA and Trimble's own protocol. The tricky part is that by the time you get the data, it is too late. So you have to synchronize (hence the pulse-per-second signal provided by good gps receivers) and use some other clock that you sync'd with to get a better 'current time'.
You need some hardware and software that will parse the transmission and extract the time and date (if you need it) and this probably exists somewhere--even for DOS, I would guess. The software is trivial, and I could probably write it myself, but I'm not volunteering to do so. (I'm not a programmer.)
I should think that an ordinary laptop would do all of this for you easily, but you could find a small engineering firm that does RF stuff and has, like all modern firms, a programmer, that would create for you whatever you need--a printed record, or whatever.
We already do all this. My original question was not really about gps at all. It was simple about a computer keeping time correct across boots. Not changing the time by, say, 8.3 hours. The gps discussion has been an aside. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.
