This structure is not part of POSIX. According to POSIX, gettimeofday() has the following prototype: int gettimeofday(struct timeval *restrict tp, void *restrict tzp); Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is not used). Remove dead error handling code. Also use NULL for a nul-pointer instead of integer 0. While there, change all pieces of code that only use tv_sec to use time(3), as this provides less overhead.
