Timeless equipment 102

So far I know these about the timeless equips:

1) They're level 120.
2) They are untradable upon equip.
3) They can "grow" like characters, and as they "level up" new stat bonus are added.
4) They grant +skills to certain skills. If the skill is maxed already, however, then the +skill part will have no effect.

Now, for the questions. How do you get these equips? What are the differences between "reverse" and (persumably) "normal" timeless weapons? How long does it take for the equips to level up?

They are dropped by Pink Vynn, and can be forged with Maker skill (but requires Time Temple etc items, possibly only dropped by Pink Vynn).
