Description: Indication of whether the system can preserve knowledge of current date and time across a system reboot.

What is swClockLostOnReboot?

This field indicates whether the device's clock is preserved across a reboot or must be reset from an external time source each time it restarts. Admins use this to know whether they need SNTP configured for time to survive reboots, or whether a manual or RTC-backed clock will hold on its own. For example, a value of true(1) tells an admin this device needs SNTP configured, since its clock resets to zero on every reboot.

Examples
