Yeah. There are many fun experiments one could do. Now I got this idea instead: what if it opened up on 07:39 PM on January 1st, but then the window moved forward 3 minutes and 56.7 seconds each day so that it was back on 07:39 PM a year later. That sounds like it would be extremely useless, but fun.

I came to say the same, and also why not let it wander around looking for an optimal time.
