Excuse me, but you need to reread and understand in what context you're trying to place time dilation. What you have contextualised in time dilation is in response to the expansion of spacetime. In which case, there is no issues regarding relativity, only as a property of expanding spacetime cosmology. So, it is you that has misunderstood your own question.
This is precisely why most people get their knickers in a twist over science when they ask questions and expect certain answers. You don't understand the science in the first place and you only paraphrase what you've read. Quoting websites isn't going to give you the answers to your questions, nor is it going to contradict the answers of others unless those others have got the answers wrong themselves. Steven knows exactly where he is coming from...his degrees are in applied maths and physics.
If you want to know about science, fine, read up about it. But if you want to understand it, learn off someone who already knows about it as well. Understanding comes through asking questions about those subjects you read. You won't get that through rote learning.
