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.
