I'm running an asus board with a pair of PIII 550s. gettimeofday is
varying wildly on the scale of a few seconds but is accurate over about
a minute, and sleep and hwclock are accurate.
#include <sys/time.h>
#include <unistd.h>
main() {
while(1) {
struct timeval tv;
gettimeofday(&tv,NULL);
printf("%lu\n",tv.tv_sec);
sleep(5);
}
}
output:
977997637
977997642
977997647
977997659
977997656
977997668
977997673
...
Any clues? The machine is scsi, with onboard adaptec. All works well
except that kde 2 that I just installed freezes after a few seconds for
"invalid time" on a getmouseblah call. kde 1.1 was fine. Running debian
potato and all up to date. I'm just looking for a quick fix. Yes .. I
probably could robustify the code a little.
