Use your phone

242
The phone could be useful, it has a clock in it.
But it does not show the correct time.

Your phone sometimes doesn't want to turn on and the only way to make it work again is to pull the battery out and put it back, but this resets the clock.
And you don't feel like setting up the clock every time this happens.
So the phone is useless as a time source.

But you noticed something else. Something interesting.
