I would prefer not to break the test here if the file is not present on
a system, there may be embedded systems where this file does not exists
and SAFE_TOUCH() will exit the test with TBROK in that case.

Also the problem is access time here, so opening and closing the file
should be enough to fix it right?

What about something as:

	int fd = open("/etc/localtime", O_RDWR);
	if (fd > 0)
		SAFE_CLOSE(fd);

That should fix the access time without breaking the test on systems
that does not have the /etc/localtime file installed.
