Not quite atomic - but an interesting Raspberry Pi project is an NTP server with a GPS unit. It doesn't take deep pockets a all and it offers far more accurate time sync than any average person needs. NTP will rate it at a lower stratum than any network-only time server.
I had one in the NTP pool for a while.
