Time settings

XBee Industrial Gateway uses Network Time Protocol (NTP) for time synchronization. Using NTP requires an external NTP time server. Time synchronization is critical to the security of the device, including validating the certificates that sign firmware update images, as well as to verify the server certificate when connecting to Remote Manager. Steps are taken to preserve a sense of the time across reboots, but the availability of an NTP server or servers is important to the long-term health of the device.

In environments where the device cannot directly connect to the Internet, you need to configure the time server setting to point to a local NTP server when accurate long-term time is required. Most users do not need to change the time server setting. If the Digi device is already connected to Remote Manager, you can adjust the time server configuration from Remote Manager.

The default time settings are sufficient for most users. See Default behavior regarding NTP time server access for more information about default behavior.
