Sorry to put a damper on once again ;( The 100ns accuracy you might get with the advertised optional 1pps (1 pulse per second) output. Your computer, Linux or not, will not be able to make use of that. The other (and only) interface being an RS232, there's no way you get anywhere close to 100ns. Expect about a few microseconds minimum error, my guess. But yes, the bottom line is, you'll never need to set your computer time again. This is the main point! When I got my own radio-fed clock in 1985 (no GPS back then), it was accurate to better than a human could percieve. That wasn't the point though - I never needed to question anyone else's clock, and all arguments in the family about whos clock was right suddenly ceased. They all laughed about me getting it - then all quietly trapsed in to set their watches... bit of a laugh that was. I've still got the 1986 model, pity it won't work in NZ.
