Can't change clock time

[Chas88]

In anticipation of the clocks changing I thought I’d alter mine tonight but when I press the button in nothing happens. Any ideas on what the cause is and how to go about fixing it?

I heard That if you hit 88mph something happens to the clock and you may go back to 1959???

I am certain that mine is constantly pointed to 'Fun Time!'

Disconnect the battery for an hour, only trouble is in March you will have to do it for 11 hours
