RTC: Functions for Real Time Clock

The clock functions allows the program to interact with the real time clock on the RTCU platform. By using these functions, it is possible to both set and read the built-in clock.

	clockGet	Reads the time-of-day.
	clockNow	Reads the time-of-day as a number of seconds since 1980-1-1 00:00:00 (LINSEC)
	clockSet	Sets the time-of-day.
	clockTimeToLinsec	Converts a time in yy,mm,dd,hh,mm,ss format to number of seconds since 1980-1-1 00:00:00.
	clockLinsecToTime	Converts a time in number of seconds since 1980-1-1 00:00:00 to yy,mm,dd,hh,mm,ss format.
	clockAlarm	Sets an alarm.
	clockDayTimer	Sets a repeating start and stop time.
	clockWeekTimer	Sets a repeating alarm on a specific weekday at a specific time.
	clockSetWakeup	Configures the system to wake from pmSuspend at a specific time.

In many of the functions, the term LINSEC is used which stands for Linear Seconds.

In the RTCU concept, a LINSEC value is the number of seconds since 1980-1-1 00:00:00.
