GNSS UTC in Date-Time menu:
The UTC time provided by the gnss module is not shown in the date-time settings menu. If a valid time signal is available then the OSTC RTC may be set to it by selecting the UTC menu entry. The time zone has to be selected manually. This is possible using a separate edit line.
