I don't think that the Time Egg would be temporary. If it changes time, in order to reverse that, it would have to reverse whatever happened in the first place. An analogy I used in another situation was with MSPaint (or any paint program, really). If you make a mark, the mark won't fade away. It requires another action to remove the mark. Also, Lordchander, you obviously didn't sleep, as you posted a few things after this post. You sure are a busy guy...
