Some manufacturers are fine adjusting their oscillator. But I think the majority are letting the oscillator free run. Then the software clock inside the GPS (sometimes called receiver time) will be reset to remain within +- some limit compared to GPS time, +- 1ms is a common choice. -- Björn _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
