Your local NTP server can be locked to GPS (ideally) or to the Internet. GPS devices: http://www.satsignal.eu/ntp/FreeBSD-GPS-PPS.htm http://www.satsignal.eu/ntp/Sure-GPS.htm The PC's screen refresh rate would be marginal for 1/00s, though. Perhaps 1/20s is more realistic. If 1/10s is good enough, there are applications like Emerald Time for your iPad/iPhone: http://emeraldsequoia.com/et/index.html Are you actually trying to timestamp a video recording or light-level reading? Or time pressing a button?
