 * \brief Rtc8 Click example
 * 
 * # Description
 * Demo application shows the operation of RTC 8 clicks.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring clicks and log objects.
 * Settings the click in the default configuration.
 * Sets new: Time, Date, UNIX time and alarm data.
 * 
 * ## Application Task  
 * Read current Time, Date and UNIX time and checks if the alarm is active.
 * 
 * @note
 * Comment out the lines for setting date and time if you would like the 
 * module to keep counting time after a reset or shut down.
