Oh, yes...time travelling...eek...in case you didn't know, time travelling can cause tons of problems with your game and your computer. There are several informative threads about it. It is true that time-travelling is frowned upon because it is considered 'cheating', but also, if you were unaware...it can be very detrimental to your game and system.
As Arnie said, for your particular puzzle, you do not necessarily need an adult chief so time travelling is no help here...but moreso, it is not needed in the entire game. The game is set up so that everything can be accomplished through normal game play and no time adjustments.
Just thought I'd let you know, in case you didn't. Good luck!
