From what I've heard, no you can't. I don't have a premium kiosk myself because I'm a free player so I can't give you any real confirmation on that other than what other players have told me.

However, I do remember that around this time last year it was able to be bought/sold in a premium kiosk. I remember seeing many people sell time warps in their kiosks. However, I believe there was some kind of glitch involving the time warps in which illegitimate time warps were "created" through a bug in the game, so the GM's probably removed it completely.
