I did find one reference to about 1.1 hours between updates. I'd assume, 
having dealt with this before when mobo clocks weren't so accurate, 
(I've had a linux only house since 1998) ntp claimed to adjust this 
interval, and later to adjust the clock's drift so it eventually settled 
to a very small error and the update rate would fall back to the 
default. No idea if this is still true, and the man pages seem to have 
been eviscerated of such info.  Sad state of affairs IMNSHO.
