That is what every Linux user says about Windows. But it's worse than just not working as well "jumping the clock" is a defective design. Any software that periodically sets the clock will break a lot of other software that tries to measure time intervals. It is simple: The way to meaue a time interval is to sample the clock, do something, then sample the clock gain. then subtract the first time from the last and then you know how long it took to do that something. Setting the clock periodically breaks this. The only thing that can work is to adjust the clock RATE by tiny amounts Now if you only need enough accuracy so that you are not late to appointments then just do "whatever". But we assume on a time nuts list that we care about milli and micro seconds at least Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
