At the most basic level, the purpose of NTP is to compute that offset
you see. That is the offset between the clock on the computer's
motherboard and a perfect clock. The offset value will change with
temperature. Try watching it for 24 hours or maybe partially block
the computer fan and see what happens in an hour. NTP keeps
recomputing the offset as your computer's clock changes with
temperature or just with age.

Thanks. I needed that NTP 101 lesson. So is it a stretch to try and
obtain a quality motherboard to improve the frequency offset?
Forget about it!! Your computer, and just about any other computer, is
not intended to be a precision clock. The crystals used in most
computer clocks flunked the quality control testing for use in a cheap
wrist watch!
This sad state of affairs is why NTP exists. It will beat your
computer's clock into submission!
