This chapter describes the OS specific part of OTP that relates to the Network Time Protocol (XNTP).

XNTP for Sunos5

XNTP maintains a Unix system time-of-day which conforms with the Internet standard time servers. XNTP is a complete implementation of the Network Time Protocol, version 3 specification as defined in RFC 1305.

XNTP for use in an embedded system running Sunos5 is delivered with OTP. The XNTP is delivered as a separate tar file which also includes extensive documentation and installation instructions.

The following section of the introductory documentation is included in the distribution:

The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for example. Typical NTP configurations utilize multiple redundant servers and diverse network paths, in order to achieve high accuracy and reliability. ...

The XNTP software is supplied without charge under the conditions set forth in the Copyright Notice provided within the distribution.
