i counted 2m38s considering the moment of spawn as start and the moment all sacrifices are confirmed as end, i tried looking for the actual timing rule but i couldnt find it, hope a moderator can count it right if i was mistaken before publishment.

in this clip the match begins ar around 2m34s and sacrifices are confirmed at around 5m11s, i included both pre-matchmaking and postgame.
