I thought about this too. But what happens if there are accidentally two
sets with same timestamp in the table? I suppose the outer select would
match both of them. But a DISTINCT should help to avoid this.
Ok, if you think this is the propper way to meet the
requirement i will do so.

Thank you for your answer!
