Configuring Daylight Savings Time
The Time Page contains fields for defining system time parameters for both the local hardware clock and the
external SNTP clock. If the system time is kept using an external SNTP clock, and the external SNTP clock fails,
the system time reverts to the local hardware clock. Daylight Savings Time can be enabled on the device.
