When you're "clocked in" you are working and getting paid. You clock in at the beginning of your shift and clock out when you leave. This is for people who are paid by the hour.

BrE doesn't really use "clocked in" as an adjective. It tends to be used just as the past participle of the verb "clock in".

Did you clock in?
Have you clocked in?
I want to see what time you clocked in this morning.
