a) try and connect to a well known time server and see if the time is too far off at commit time. May or may not work.This would require some external program tho, wouldn't it?It's called ntpq, and I believe most people should have it installed[snip] Should doesn't mean they will tho. :) And the first time you assume everyone has something, 5 people pop up screaming 'cuz they don't.
No, but as I said, the protocol is trivial if you want a very approximate time (use NTP v3 since all V4 servers I know support it). The problem is finding the closest server, not sending an UDP packet and decoding the answer and giving up if you don't receive anything after 5 packets or so. I'm almost certain there is database of servers somewhere, but I just don't remember where (between 2 cesium clocks, one hydrogen maser, 2 GPS and one radio receiver I have enough references for my use at the telescope ;-)). I also don't know whether some people could be blocked from using NTP, but I don't think that it is a satisfactory solution in any case. Regards, Gabriel. ** Sent via the linuxppc-dev mail list.
