	// It is generally safe to read `AttrTime` without locking because if some other
	// operation is modifying `AttrTime`, in most cases the reader is okay with working with
	// stale data. But Time is a struct and modifying it is not atomic. However
	// in practice (until the year 2157) we should be okay because
	// - Almost all uses of AttrTime will be about comparisions (AttrTime < x, AttrTime > x)
	// - Time object will have Time::monotonic bit set (until the year 2157) => the time
	//   comparision just compares Time::ext field
