SMΩRF has built-in Real Time Clock (RTC) to allow to mark backups with date signature as well as to provide
UTC and local time/date for screen saver. Special feature is that RTC can be synchronized by internet clock
reference and keep time in the SMΩRF updated and very accurate. This menu allows to set time and date, its
format as well as synchronization parameters.
