/// RealTimeClock is an interface to the mbed RTC module
///
/// It provides interfaces to get and set the time in text representation
/// as well as a means to get and set the timezone offset so that it
/// maintains time in UTC format.

///
/// @note It is recommended that the system has a battery connected to
/// the mbed battery backup pin.

/// Example:
/// @code
#include "mbed.h"
#include "RTC_IUT.h"
