It would be great if there was an in-built feature in Construct 2 to add a graphical timer object in a HH:MM:SS format, whether for countup or countdown.
It's a core gameplay feature of very many games.
The only way to do it now is either completely manually(which can be a bit confusing for us new ones) or using Plugins(which havent been updated in a while and can give errors with Construct 2 updates).
