Confused by boiler timer

NewHere_2

Please could someone explain what the timer on my boiler is saying in the photo? It's really old and I don't understand where to place the pins - all I know is the outer circle is 'Off' and the inner circle is 'On'...

Thank you!

Cant see any photo, but out is usually off and in is on.

There will also be a three position switch on the clock, On/Off/Timed
On = Thermostat controlled (temperature around thermostat is less than set temp, it will turn on)
Off = Off
Timed = On during the times set on the clock, when temperature below set temp on the thermostat.

If you want it on at 7am, stick the pin in the On hole at 7

If you want it off at 8am stick the pin on the Off hole at 8
