Mt10 mechanical timer - Worcester bosch

Hello, I have a mt10 mechanical timer on my boiler. How can I tell if the clock is am or pm. Is there a way or is it a design flaw?

many thanks in advance.

It's just that the pins used to set the on or off periods is 24 hours. So if it the heating is set to come on at 4am say. Then because there is no indication of whether the clock is am or pm. It may actually be 12 hours out and the heating comes on at 4pm as opposed to 4am.

Ah I think it's ok, theres a little arrow. Not obvious at first!

The numbers on the outside (rotating part) use the 24hr clock. The 12, 3, 6 and 9 on the inside are fixed. The arrow points to the current time.

There is a short video on how to set the timer on the Worcester-Bosch website:
