Summary

Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks.

This chapter of the user manual provides an overview of the NTP page for RUT850 devices.

General

The Time Synchronization section is used to configure general router time settings, like selecting the local time zone, setting a time update interval, synchronizing the time and more.

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 router.
Time zone time zone; default: UTC The router will sync time in accordance with the selected time zone.
Enable NTP yes | no; default: yes Turns NTP on or off.
Force servers yes | no; default: no Forces unreliable NTP servers.
Update interval (in seconds) integer; default: 3660 Defines how often the router will update the time.
Save time to flash yes | no; default: no Saves last synchronized time to flash memory.
Count of time synchronizations integer; default: none The amount of times that router will perform time synchronizations. Leave empty in order to set to infinite.
Operator Station Synchronizations yes | no; default: no Turns synchronization with mobile operator on or off.
Count of failed NTP requests integer; default: none The amount of times that router needs to fail to send NTP requests before launching operator station synchronization. Empty value - 5.
GPS synchronization yes | no; default: no Enables periodic time synchronization for the system using the GPS module (does not require an Internet connection).
GPS time update interval 5, 30 minutes | 1, 6, 12, 24 hours | 1 week | 1 month; default: Every 24 hours Defines how often the router will update the time using the GPS module.
Offset frequency integer; default: 0 Adjusts the minor drift of the clock so that it will run more accurately.

NTP Server

The router 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.

Time Servers

The Time Servers section displays the NTP servers that the router 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.
