Nothing happened! I'm still here!

No, wait, the clock on the wall, it's three hours later! Did I fall asleep? Was I in some sort of trance? But my pocket watch hasn't changed. I did it! I travelled in time! The machine works!!!!!

Should I push the lever a little further?? Or should I push it all the way? Or pull it backwards and try to go back in time? Or do something else?
