* Function: BOOL RtccWriteTime(const rtccTime* pTm, BOOL di)
*
* PreCondition: pTm pointing to a valid rtccTime structure having proper values:
* - sec: BCD codification, 00-59
* - min: BCD codification, 00-59
* - hour: BCD codification, 00-24
* Input: pTm - pointer to a constant rtccTime union
* di - if interrupts need to be disabled
* Output: TRUE '1' : If all the values are within range
* FALSE '0' : If any value is out of above mentioned range.
* Side Effects: None
* Overview: The function sets the current time of the RTCC device.
* Note: - The write is successful only if Wr Enable is set.
* The function will enable the write itself, if needed.
* Also, the Alarm will be temporarily disabled and the
* device will be stopped (On set to 0) in order
* to safely perform the update of the RTC time register.
* However, the device status will be restored.
* - Usually the disabling of the interrupts is desired, if the user has to have more
* precise control over the actual moment of the time setting.
