13.9 Checking time server information

The system clock on the U-router NGW is synchronized by a process called:

systemd-timesyncd

This time synchronization takes place with remote servers AND with the local time server that is

synchronized with the mobile network time. To see the status of the time synchronization you can

use the following command:

systemctl status systemd-timesyncd

For example:

root@VZ1-034748:/home/rfi# systemctl status systemd-timesyncd

●

systemd-timesyncd.service - Network Time Synchronization

Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled; vendor preset:

Main PID: 220 (systemd-timesyn)

Status: "Synchronized to time server 127.0.0.1:123 (127.0.0.1)."

Nov 06 18:18:46 rfi-000102 systemd-timesyncd[220]: Synchronized to time server 127.0.0.1:123

(127.0.0.1).

In the example above, there are three time servers configured:

•

127.0.0.1, the internal time server, synced to the mobile network

•

213.251.52.43, external time server on the Internet

•

91.236.251.11, external time server on the Internet

From the output of the command we can see that the system clock on the U-router NGW is

synchronized with the mobile network time. Furthermore, the two remaining external time servers

are not reachable.
