Summary #

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 RUT240 routers.

The information in this page is updated in accordance with the RUT2XX_R_00.01.12 firmware version.

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, etc.

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

Current system timetime; default: noneCurrent local time of the router.
Time zonetime zone; default: UTCThe router will sync time in accordance with the selected time zone.
Enable NTPyes | no; default: yesTurns NTP on or off.
Force serversyes | no; default: noForces unreliable NTP servers.
Update interval (in seconds)integer; default: 3660Defines how often the router will update the time.
Save time to flashyes | no; default: noSaves last synchronized time to flash memory.
Count of time synchronizationsinteger; default: noneThe amount of times that router will perform time synchronizations. Leave empty in order to set to infinite.
Offset frequencyinteger; default: 0Adjusts 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.
