Figure 11. Time setting sub-page
Current time: This shows the current time used by the unit. The time is displayed in local time with an indication of the local time zone relative to UTC.
Time zone: Here it is possible to configure the local time zone to operate in. The time zone is specified in hours offset to UTC. All time stamps in the GUI are displayed in local time. If you switch time zone during operation, the alarm log entries will also be updated to reflect the new time zone. The alarm log export option prints the time zone at the time of the export at the top of the log.
Clock source: Select the synchronizing source for the device real time clock. The options are SNTP and Internal. In SNTP mode the clock is retrieved from a specified server, in Internal mode the clock is maintained locally by the device. Remark that the clock value is not kept after a reboot when running in Internal mode. To synchronize the alarm logs on several devices it is recommended to use a SNTP server.
SNTP server address: The IP address of the SNTP server entered as four decimal triplets separated by decimal points (full stop/period) e.g.
10.40.81.10.An example on a SNTP server is the Windows Time Service built into the MS Windows operating system. The SNTP protocol runs on UDP port 123, which must be let through in eventual firewalls.
