Mingham-Smith Ltd. 1994-2005 3 Welcome to Tardis 2000 Tardis 2000 is a utility for Windows that makes sure your PCs clock tells the right time. It can find out what the right time is in various ways including using networked timeservers, GPS (The Global Positioning System), Radio clocks, and by listening for time broadcasts over a LAN. Tardis 2000 requires the TCP/IP networking protocol to be installed. The service version of Tardis 2000 runs as a Windows “service”, just like other services that come as standard with Windows. It acts as both a server and client for the supported protocols. I.e. it can get the time from a timeserver with the correct time and then make the correct time available to local clients. Tardis 2000 running on a central server can be used as a master time source for the domain by running Tardis or K9 on the other workstations of the domain using the server machine as the timeserver. See page 63 for details of K9. Tardis 2000 can use the following time protocols RFC868 (Time) RFC867 (Daytime) RFC2030 (SNTP) Broadcast NTP HTTP protocol. Kallisto GPS. NMEA compliant GPS cards.

If your PC runs Windows 95/98/ME you will only be given the option to install the Application version of Tardis. If you use more recent versions of Windows you have the option of using either the application version or the service version. We recommend that you use the service version. Both versions have essentially the same functionality. The difference is that the application is a stand- alone utility; the service version is a control panel and
