USNO NTP Network Time Servers. The Naval Observatory operates an ensemble of stratum 1 NTP servers which are synchronized to the USNO Master Clocks or to GPS as their stratum 0 reference clocks. Network Time Protocol (NTP ) is an Internet standard protocol which enables client computers to maintain system time.

This driver supports the US (NIST and USNO) and European (PTB (Germany), NPL (UK), etc.) modem time services, as well as Spectracom GPS and WWVB receivers connected via a modem. The driver periodically dials a number from a telephone list, receives the timecode data and calculates the local clock correction.
