The information in this page is updated in accordance with firmware version RUT9_R_00.07.01.1.

Summary[edit source]

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 RUT950 devices.

General[edit source]

The Time Synchronization section lets you select time zone 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.

NTP[edit source]

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

NTP Client[edit source]

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.
Operator Station Synchronization off | on; default: off Synchronizes time with mobile operator's base station.
Hostname ip | url; default: 0.openwrt.pool.ntp.org NTP servers that this device uses to sync time.

NTP Server[edit source]


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:

NTPD[edit source]

The NTPD program is an operating system daemon that synchronizes the system clock to remote NTP time servers or local reference clocks. NTPD includes the ability to use this to keep your clock in sync and will run more accurately than a clock on a device not running NTPD. NTPD will also use several servers to improve accuracy. It is a complete implementation of NTP version 4 defined by RFC-5905, but also retains compatible with version 3 defined by RFC-1305 and versions 1 and 2, defined by RFC-1059 and RFC-1119, respectively.

Field Value Description
Enable NTPD off | on; default: off Turns NTPD on or off.
Enable NTP config from file off | on; default: off Run NTPD with uploaded configuration file.
NTP configuration file .conf file; default: none Upload a custom configuration file.
Server ip | url; default: 0.openwrt.pool.ntp.org NTP servers that this device uses to sync time.
Enable Server off | on; default: off Enables NTPD server to make the router act as an NTP server so that it can provide time synchronization services for other network devices.
