Always check return codes. gettimeofday() *can* fail (most likely,
tv1 and/or tv2 are bum pointers that don't point where you think).

If both calls are actually succeeding, you might want to do this:
printf("tv1=%d.%d tv2=%d.%d\n",tv1.tv_sec,tv1.tv_usec,tv2.tv_sec,tv2.tv_usec);
So you can see which valye is bogus (rather than trying to look at the difference
and tell from that...)
