Hello,

since this commit

https://github.com/freebsd/freebsd/commit/307f787e5a7f

tc_get_timecount() is called two times in tc_init().

/*
  * Initialize a new timecounter and possibly use it.
  */
void
tc_init(struct timecounter *tc)
{
[...]
	if (tc->tc_quality =3D=3D timecounter->tc_quality &&
	    tc->tc_frequency < timecounter->tc_frequency)
		return;
	(void)tc->tc_get_timecount(tc);
	(void)tc->tc_get_timecount(tc);
	timecounter =3D tc;
}

What is the reason for this procedure?
