Yes, with some work: http://time.qnan.org/ Does the FR have access to the PPS signal from the GPS chip? That might get it down to tens of microseconds of clock jitter. :) It looks like gpsd should work as well. Plus, ntp can fall back on NTP over GPRS/wifi/usb if it's been a while since the last GPS connection. It can also set the hardware clock skew so it drifts fewer minutes per day when there's no network or sky. I wonder how hard it would be to add GSM time broadcast support to NTP... -Rusty > Stefan Schmidt schrieb: > | Hello. > | > | On Thu, 2008-08-14 at 23:48, Matt wrote: > |> Isn't time available via GSM broadcasts? > | > | Sometimes.
