Since long (8 bytes) is the largest atomic type supported by Java, this would have to be represented as a String (or rather BytesRef) and would take up 4 + 32 bytes + 2 * 4 bytes from the internal BytesRef-attributes + some extra overhead. That is quite a large memory penalty to ensure unique timestamps.
