Until you have read and understood Dave Mills' book on the subject, just
consider the defaults to be mandatory!
David L. Mills, "Computer Network Time Synchronization: The Network Time
Protocol on Earth and in Space, Second Edition"
The useful poll intervals range is, for most purposes, from four to ten,
which being translated, means from 16 to 1024 seconds! The software
will select a value in that range and adjust the value as conditions change.
I think of the low poll ranges as correcting errors quickly while the
long poll intervals correct small errors very accurately.
