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

Based on a sample of one (my NTP), I can hold the clock frequency to 0.1PPM. Seems to me you could compute the adjustment requirements from such a number.

Sure enough every 4 seconds would work, as would every 2 seconds.  But I
bet every 1000 seconds would work as well.

We need some more details but it seem he has something badly misconfigured
if 4 seconds updates are required.
