NTP Server Highly Recommended
Raspberry Pi-based devices like NComputing RX420(IGEL) have no battery-backed real-time clock. After a power outage, the system time will reset to the build time of the IGEL OS firmware. If the time and date are not correct, certificate issues may arise, which causes problems with websites, for instance.
Therefore, it is highly recommended to specify an NTP server. When an NTP server is configured, the system is always provided with the correct time and date.
To configure an NTP server via a UMS profile, edit Use NTP time server and NTP time server under System > Time and Date. For details on profiles, see Using Profiles.
