    Peter can see a clock in the mirror from the place he sits in the office. When he saw the clock shows 12:22, he knows that the time is 11:38.

    in the same manner:

    05:25 --> 06:35

    01:50 --> 10:10

    11:58 --> 12:02

    12:01 --> 11:59

​

    Please complete the function WhatIsTheTime(timeInMirror), where timeInMirror is the mirrored time (what Peter sees) as string.

​

    - Return the real time as a string.

    - Consider hours to be between 1 <= hour < 13.

    - So there is no 00:20, instead it is 12:20.

    - There is no 13:20, instead it is 01:20.
