#ifndef GB_TIME_H
#define GB_TIME_H

/*this file, if included instead of <stdio.h> has the following functionality:
1) if GB_TIME_INTERCEPT is defined then
    a) some of the time.h symbols shall be redefined, for example: time => gb_time
    b) all "code" using the time will actually (because of the preprocessor) call to gb_time
    c) gb_time shall blindly call into time, thus realizing a passthrough
    
    reason is: unittesting. time comes with the C Run Time and cannot be mocked (that is, in the global namespace cannot exist a function called time

2) if GB_TIME_INTERCEPT is not defined then
    a) it shall include <time.h> => no passthrough, just direct linking.
