**  DESCRIPTION :  Include file with prototypes and macros for 		  *
**		   manipulating time.                                     *
**		   The low level time routine _time() strongly depends    *
**		   on the hardware , so this routine should be customised.*
**		   To determine the time in seconds, the value returned   *
**		   by the _time() function should be divided by the value *
**		   of the macro TICKS_PER_SEC.                            *
**                                                                        *
