* \brief Production date application

* from the battery backup. This application reads out the production date from
* EEPROM and shows the difference between the current time and the production
* date; in other words the time the RTC timer has been running on battery
* since production.
*
* \note If the EEPROM is erased and no production date can be set, it will
* default to time 01.01.1970, the start of the UNIX time epoch.
