The electric clock has stopped working. It is situated on the right hand side of the control panel as you look at the oven. The clock has buttons for starting and timing cooking. There are also 3 circular control knobs for controlling the grill, the grill oven and the main oven. Everything is working normally except the clock.
The control panel is metallic brown in colour.
Any advice would be much appreciated.

That looks like a pretty old cooker. Spares may be sparse. See:

It MAY be that a component in the clock has failed, very possibly the X-Capacitor but you'd need to a) be able to dismantle the cooker to get the clock out b) dismantle the clock to look, c) have a rough idea how to diagnose and d) know what you are doing to order a suitable (safety critical) part and fix it.

If you have a tame electronics engineer to hand you may be lucky (and I said electronics, not electrician :-) )
