Kirakira san, since we are talking about 時 I have a question. It is something I have noticed and actually I have noticed the same thing for ため as well. The particle に after 時 (take the 2 phrases used as example in this thread) is optional? I mean, I have seen many times 時 used as "when", but not always it has the に after it. Now, being 時 a time marker, it should always have に after it, but as I said I have noticed many times it is not used it.
