Have you even read the rules? It clearly says the following: "The timer starts when the in-game countdown ends.", meaning as soon as the countdown timer in-game hits 0 and the first dummy spawns, you start the timer. Please read the rules before asking next time.

It is a way to stop cheaters from editing their gameplay (like dream)

i have a slight suspicion that this is sped up

please use a timer overlay next time

@deadlyghoul Please use a better timer next time.
