void timezone_init ( void  )

get and set timezone stored in EEPROM

This function will check if a timezone has been stored in EEPROM. If this is the case it will be set, and used by the date&time application. If it is not set, the "select timezone" application will be started to set it

void timezone_select_application ( void  )

Select timezone application.

This application will show a menu with available timezone offset and set the selected timezone to be used by the date&time application. If the timezone setting differs from the already stored setting in EEPROM, the EEPROM value will be updated with the new selection.
