Be aware of asymmetric routes between your machine and these servers. Asymmetric routes can add a noticable time offset. Closer physical locations may not always be the best server to use. It is possible to syncronize to a server more than halfway across Canada with an accuracy under 1 ms, given reasonable networking conditions.
