No. Outside of time is "atemporal". "Eternal" inside time but forever.
Se your own example from wikipedia:
Good grief. I'm dealing with two people who don't understand this system, but want to lecture me about it.
"Existing forever, nor mortal, of limited duration'" are references to time. Your quoted sentence specifically states that forms are NOT eternal in that sense.
There are conceptions of eternity in time, such as the classic Christian variety. This is different. It was a reconciliation of Heraclitus, who argued that change was constant, and Parmenides, who argued that change was illusory. Plato proposed a duality: material things change, but the laws which govern them do not.
You are delusional. This is gibberish. I dont think you have a clue what you talk about.
