* ELAPSED TIME INITIALIZATION

* Description : This function initialize the elapsed time module by determining how long the START and

* to account for the processing time of the START and STOP functions.
* Needs to be called only once before any of the timers is started with PC_ElapsedStart().
*
* Arguments : None.
*
* Returns : None.
