Chapter 1: General Information Overview of TimeVault

1.2 Overview of TimeVault

TimeVault is a high-performance, internet-enabled Network Time Protocol (NTP) server

that operates in a secure access environment and provides time to multiple clients with

extreme accuracy. To provide trusted time and guard against any denial of service,

TimeVault uses GPS as a primary synchronization source, backed up by ACTS and NTP

as secondary and tertiary sources, respectively.

TimeVault provides network time synchronization over Ethernet connected networks via

Network Time Protocol (NTP), developed by Dr. David Mills at the University of

Delaware. TimeVault currently supports versions 2 and higher of the NTP, RFC-1305, as

well as the Simple Network Time Protocol (SNTP), RFC-2030. In addition, TimeVault

responds to TIME protocol requests, RFC-868. For details about these protocols, refer to

Appendix A and Appendix B in this manual.

The main feature of TimeVault’s web interface is its ability to perform setup and control

operations from a remote location, using the Internet or TCP/IP LAN (see Chapter 3). The

protocol used is either Telnet or HTTP. TimeVault has an RJ-45 Ethernet connector on its

NET Port, providing NTP and IP access, and a 9-pin D serial connector for serial

input/output.
