[time-nuts] Is it sensible to update every few seconds from NTP server?

I think it might be JT65 he is using. I know he said that if your time
was accurate to 1 ms, and someone elses 2 ms, you have a higher chance
of making the QSO. Hence there is a need for accurate timing. (I'm not
sure he said those exact figures of 1 and 2 ms, but the general point
was that it needed to be accuate, and increased accuracy gave a higher
chance of making the QSO).

But the whole idea of getting time from an internet time server every
few seconds seemed odd to me. He is not using any local time server.

I'll try to find out what mode he is using, and what software to
correct his time.
