[ts-7000] TS-Linux difftime

[Mike Dodd <>]

I wrote a C program that compiles and runs on a TS-7250 under Debian and
under TS-Linux, but difftime() doesn't operate correctly under TS-Linux.
Here is a test program:

---------------
struct tm *tp = NULL;
time_t t_now;
time_t t_last;
double elapsed_seconds;

t_last = time(NULL);

while(1)
{
   t_now = time(NULL);

   elapsed_seconds = difftime(t_now, t_last); // Get time through loop
   t_last = t_now;
   printf("t_now = %ld, t_last = %ld\n", t_now, t_last);
   printf("elapsed_seconds = %1.1f\n", elapsed_seconds);

   sleep(5);
}
---------------

Under Debian, I see the expected 5 seconds for elapsed_seconds each time
through the loop. But under TS-Linux, elapsed_seconds is always ZERO.
The t_last and t_now variables are being updated correctly -- 5 seconds
difference each time -- but the TS-Linux difftime () returns zero.

This is the exact-same code running on Debian and TS-Linux.

Anyone know what's going on?

Thanks for any pointers.
