Configuring date and time
We recommend that you use NTP time synchronization for configuring the date and time.
To use Network Time Protocol (NTP) time synchronization
1. Choose Administration > System Settings: Date and Time to display the Date and Time page.
2. Under Date and Time, click Use NTP Time Synchronization.
3. As a best practice, you should configure your own internal NTP servers; however, if you want to use the Mobile Controller-provided NTP server, the hard-coded IP address that is preconfigured into every Mobile Controller is 208.70.196.25. This IP address appears in the NTP server list.
4. To add a new NTP server, complete the configuration as described in this table.

After you apply your settings, you can verify whether changes have had the desired effect by reviewing related reports. After this verification, you can write the active configuration that is stored in memory to the active configuration file (or save it with any filename you choose). For details on saving configurations, see Managing configurations.
