Most gmtime implementations return a NULL value when they encounter an error (and this behavior is specified by ANSI C and POSIX). FreeBSD's implementation, however, will simply leave the "struct tm" untouched. Let's also recognize this and convert it to a NULL (with this patch, t4212 should pass on FreeBSD).
