How can I change the time on my boiler.
It’s a Worcester Bosch model 28SI 11

What did you find when you did your own G**gle search for a manual? The only manual I could find fo ryour boiler doesnt show any clock on the boiler:

Is your timer ON the boiler? If not, what make and model is your timer?
