Tests not passing

My code works in my Go workspace but it's not passing the tests.

func (h *Hours) increment() Hours { return (*h + 1) % 24 }

src/clock/hours.go 
package clock

type Hours int

func (h *Hours) Increment() Hours {
  return (*h + 1) % 24
}

You were probably testing only the return value, which would make it appear to be working.

But the challenge instructions say "Have it modify the receiver directly", and "Don't forget: to ... modify the value at that pointer."

So you need to modify the value first, and then return it. And for testing, use the second example in the challenge.
