It's wrong because gettimeofday() doesn't fill in a struct timespec;
it fills in a struct timeval. You basically made random
(non-type-safe) changes to the program until it compiled; luckily for
you the layour of struct timeval and struct timespec are similar.
If you want to use the POSIX.4 interface, you need to use
clock_gettime(). However, the reality is that gettimeofday() is more
portable than clock_gettime(), simply because not all OS's have
implemented all of the POSIX.4 interfaces, whereas BSD and System V
derived systems (which basically covers everybody) has gettimeofday().
The real issue was a missing #include of <sys/time.h>.
