Changing hour can't change hour from 10:00 from 8:07 pm to 10:08 pm.

On that type of clock, (I have similar), you just move the hours forward 12 hours. There is an indicator that shows AM and PM. You will see it change as you scroll past 12:00.

I did mine this morning.

Hi there, it doesn't seem as if there's any manuals or instructions for fixing anything with this toy. I looked on the Hasbro website, and it seems you can do a live chat with them between these hours:

Monday: 08:00 AM - 05:00 PM EDT
Tuesday: 08:00 AM - 05:00 PM EDT
Wednesday: 08:00 AM - 05:00 PM EDT
Thursday: 08:00 AM - 05:00 PM EDT
Friday: 08:00 AM - 12:30 PM EDT

I've included the customer service website as a link. Good luck!

The conditions of the PM display consist of the codes of the setting mode (08) for "the setting value
treated as a threshold of the PM display", "the counter indicating the current number of prints and
driving time" and "the setting value which determines the display conditions".

08-6190: Setting value of PM counter [process unit (K)]
08-6191 : Setting value of PM time counter [process unit (K)]
08-5554 : Setting value of PM counter [developer material (K)]

The counter indicating "current number of prints and driving time" used for the PM display function is
reset by entering "0" in it or clearing it in the PM support mode.
