A time server tool automatically starts up with the startup of Trimble 4D Control Server. It puts time information at the system’s disposal and sends events through the system on new hour, new day etc. In the status bar, it displays the current date and time in a selectable time format.
Per computer, only one time server is running. The time server tool searches for time information by the connected receivers and uses the time from the first GNSS Receiver or NMEA Receiver module in a Container, which receives GNSS data. The time server offers a proper and exact time synchronization between the time servers on this Container and its parent Controller. Other Controllers and Containers, which have no own time source (that is, no receiving GNSS Receiver modules) are then also synchronized.
If during runtime the GNSS receiver stops sending time data, the time is taken from the next GNSS Receiver or NMEA Receiver module in this Container or, if not available, from another GNSS Receiver/NMEA Receiver module in the system. If receiver time is not available in the system at all (for example, at startup), the time server uses the current computer time (which is the time of the first Container in the system that has provided computer time information) until a GNSS Receiver or NMEA Receiver module makes receiver time available (again).
The Time Settings category of system properties is a group of read-only settings. It is used to provide information on the time settings to you.
The status bar displays the current time in a selectable time format. In Trimble 4D Control Server, the time is mostly displayed as GPS time. At the rare locations, where computer (local time) has to be used (for example, for the Disk Watch module), the different time system is indicated explicitly.
Tip - The time synchronization is done using the computer SNTP (Simple Network Time Protocol) server. Using external tools you can use the SNTP server, for example, to synchronize computer time with receiver time.
