compare

var IgnoreTimestampUpdates = cmp.Comparer(func(x, y metav1.Time) bool {
	return x == emptyTime && y == emptyTime ||
		x != emptyTime && y != emptyTime
})

IgnoreTimestampUpdates ignores timestamps when testing equality, unless one is empty and the other is not.

This is used to test R*Sync equality, because the timestamps get updated every time, even if nothing else changed.
