Why do you stick to clock() or time() functions?
Throw in a CDB, then call CLK_getltime() and/or CLK_gethtime() in a
task(not in main())

I'm new to DSP Programming.  I've got a dsp system board that I'm not
in complete control of, but am doing a bunch of programming on.  I'd
like to know if there is an easy way of enabling the C library function
call to clock()?

The help file in code composer studio indicates that I'd have to write
my own handler, but I have no idea how I might even begin to support
the back end of that function.

I am also interested in knowing if it would be possible to support the
time() function call, as it would simplify some of the things I'm doing
significantly.  I have found it interesting that even though the call
does not seem to work correctly, it tries to use some offset of 8 hours
from GMT.

time_t timer;
time(&timer);
fprintf(tx,"\t        clock() = %u\r\n",clock());
fprintf(tx,"\t       GMT Time = %s",asctime(gmtime(&timer)));
fprintf(tx,"\t     Local Time = %s",asctime(localtime(&timer)));

    clock() = 4177131769
   GMT Time = Wed Nov 24 02:35:04 2032
 Local Time = Tue Nov 23 20:35:04 2032

When I am connected via the JTAG emulator, the time() function returns
the correct system time, but the clock function continuosly returns
zero.  When I disconnect, the clock() function increases the number it
returns untill it gets to the maximum number I listed above, and the
date goes out to 2032.

If the clock() function wrapped when it got to the maximum value, it
might do for what I need, but I'm mainly looking for any solution.
