Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. This chapter is an overview of the NTP section for RUTX11 devices.


The Time Synchronization section lets you select time zone, enable GPS synchronization and synchronize the time.

The figure below is an example of the Time Synchronization section and the table below provides information about the fields contained in that section:


Field Value Description
Current system time time; default: none Current local time of the device.
Sync with browser -(interactive button) Click to synchronize device time to browser time, if your device time is not correct. Note - to synchronize to correct time zone you first have to click Save & apply, as Sync with browser button checks currently saved time zone.
Time zone time zone; default: UTC The device will sync time in accordance with the selected time zone.
GPS Synchronization off | on; default: off Enables periodic time synchronization for the system using the GPS module which does not require an Internet connection.


This section is used to configure NTP client, server and time servers.

NTP ClientEdit


Field Value Description
Enable NTP Client off | on; default: on Turns NTP on or off.
Force Servers off | on; default: off Forces unreliable NTP servers.
Update interval (in seconds) integer; default: 600 Defines how often the device will update the time.
Offset frequency integer; default: 0 Adjusts the minor drift of the clock so that it will run more accurately.

Time serversEdit

The Time Servers section displays the NTP servers that the device uses. You are provided with 4 default time servers (as seen in the example below), but you can also add custom time servers by clicking the "Add" button or you can edit the given time servers.


NTP ServerEdit

The device can also act as an NTP Server, providing clock synchronization to other devices in the network. From this section you can turn this feature on or off:
