On the back of the clock, near the base and in the centre you should find a reset button. This might be a small hole in which a button can be seen to be located. Using a biro or pencil point press in the button and hold it for a minute or so. This should reset the clock to zezo time and a date of 1st of the 1st. The clock should now reset to the correct date and time. This might take a hour or so. Good. luck
