All's not what it seems

Time, gentlemen, please

Ahmed Mohamed, a 14 year old schoolboy from Irving, Texas, was suspended from school for three days after taking in a homemade clock, to show his engineering teacher what he could do.

He was interviewed by the head teacher and four police officers. According to police spokesman James McLellan, throughout the interview the boy maintained that he had built a clock, but was unable to give a broader explanation as to what it would be used for.

I think I can help the police here. It can be used to tell the time.
