SET INTERVAL TIME between checkpoints

Hey guys! I built a checkpoint system and everything bla bla (lap timer, race timer), the last thing that i need is to check how much time i’m gaining or wasting between every checkpoint ( for example +00:00.230 or -00:01.430) can someone help me??? thanksssss guys!

Working on updating an actor component I made to accommodate this. Figured it would be a really good addition to what I already created. When I finish it I will post a link to the update here. For now this is what I have, let me know if this is interesting to you and if so I will get you the updated code before I make a new video showcasing the feature.
