I don't understand, why the goto is required here. 

If you move these two cases in front of case "TIME_OK" and
omit the break, you can remove the goto and the label "start_timer".
Don't forget the /* fall through */ comment then.

If you want to keep this patch a simple code movement,
maybe add a later patch to improve this on top of it.
