When GPS is not available, an external timer server can be set as a backup.
From the CompuSync software, select the “Timeserver” tab in the “Options” window to view the current server settings, including server, protocol and port number used to communicate with the timeserver.
The current settings are used to set the initial test conditions. The default timeserver is set to the NIST in Boulder, Colorado. A list of alternative timeservers can be accessed by clicking the “Directory” button. Default settings are also selected for “Connection” and “Protocol”, but can be updated according to your preferences.
Pressing the test button will verify that the communication can be established with the current settings. To test your connection, click “Test”. The “Timeserver Test” screen will appear. Click the “Test” button in the lower left corner. The results are displayed on the bottom of the window.
