    help programming an analogue clock

    Hi, I am trying to write an OpengGL program which displays the current time on an analouge clock interface. I have drawn the clock, but I have no idea how to implement function such as time(),gettimeofday() and ctime. Any tips or hints to get me started will be greatly appreciated.

    i hate to just give out answers but i dont have time to explain right now so make sure you understand what is happening before you hit paste

    Code:
    #include <time.h>
    ...
    
    time_t curTime =  time(NULL);
    int hours = ((curTime / 3600) % 24) - 7;
    int mins  = (curTime / 60) % 60;
    int secs  = curTime % 60;

    "int hours = ((curTime / 3600) % 24) - 7;"

    this one gives weird number, for example, at 1 am now, it gave me 8?? What does it mean?

    This comes down to the "understanding it before you use it" part. The number you get is MST. You'll have to adjust the offset for whatever time zone you want.
