Hello

I'm interested to know if anyone has worked out how to update the system clock from a GPS so that more accurate timings can be recorded within Astro IIDC?

I'm going to be at a site which has no net connection and would like access to an improved clock somehow.

Worst case scenario, I could probably pipe the contents of the GGA string via sed to date, of course this is only accurate to the nearest second, but its better than nothing.

Anyone else got any other ideas? I was thinking I could also perhaps use the MSF beacon at 60kHz tied into an Arduino to give a usb time feed.

Any/all hints are welcome!
