xtime: Call tzset() from main() instead of lazily
POSIX specifies[1] that If a thread accesses tzname, daylight, or timezone directly while another thread is in a call to tzset(), or to any function that is required or allowed to set timezone information as if by calling tzset(), the behavior is undefined. So calling it lazily from arbitrary threads is risky. [1]: https://pubs.opengroup.org/onlinepubs/9699919799/functions/tzset.html
