Brian,

Ask your question on comp.protocols.time.ntp.

Meanwhile, have a look at what's in your drift file. If the number is close to 500 or -500, delete the file and restart ntpd.

If after some time (an hour or two) the file contains such a large number again, the frequency of the clock on your motherboard is too far off for ntpd to be able to correct it. Either that or you are losing interrupts (unlikely).
