If you want to change the setting of the internet time servers, select "**Internet clock**". 

This page is used for the synchronization of the unit date and time with an internet clock. Begin by selecting the check box for **Use Internet clock**. Next, enter the IP addresses (or complete address names) of the primary and secondary NTP servers. Use the Primary NTP server and Secondary NTP server boxes for this purpose.

- Here you can change the **names or IP addresses** of the primary NTP server and the secondary NTP server. The default setting of the servers is "time.nist.gov" and "tak.cesnet.cz".
- Be sure to click the "**Apply**" button for any changes to become effective.

> ⚠️ The reservation unit requires automatic synchronization of its clock with the internet time (NTP) servers.
