atomic time clock sync

Working w/ time-sensitive data, and need either a way to communicate directly with one of the US atomic time servers or to be able to flag the Windows OS to do so with an API call (or any method using code). Anybody have any suggestion or a place I could start? Any help would be appreciated.

I remember a previous forum conversation about NTP if it helps here

Yeah, just found it Carl. Thanks!
