      testMktime.c

DESCRIPTION -
	     mktime() converts the time represented by the  tm  structure
	     pointed  to  by  timeptr into a calendar time (the number of
	     seconds since 00:00:00 UTC, January 1, 1970).
	     RETURNS the specified calendar time.  If the calendar time
	     cannot be represented, the function returns the value (time_t) -1.
	     
	     ctime:
	     This routine converts the calendar time pointed to by timer 
	     into local time in the form of a string. It is equivalent to:
	     asctime (localtime (timer));
	     RETURNS the pointer returned by asctime() with local broken-down
	     time as the argument.
	     
	     assert:
	     If an expression is false (that is, equal to zero) the 
	     assert() macro writes information about the failed call to
	     standard error in an implementation-defined format. It then
	     calls abort().
	     The diagnostic information includes:
	         -the text of the argument
		 -the name of the source file
		 (value of preprocessor macro __FILE__)
		 -the source line number 
		  (value of preprocessor macro __LINE__)
	   
	     strcmp:
	     This routine compares string s1 to string s2 lexicographically.
	     RETURNS an integer greater than, equal to, or les than 0,
	     according to whether s1 is lexcicographically greater than,
	     equal to, or less than s2, respectively.

	     To run this code invoke the function testMktime().
