Basscon pool party - will there be set times?

Never been to a pool party or dayclub before. Coming in from the UK.Mainly want to see sub zero project will we get set times before hand. I know i cant deal with 35 degree C + (90 deg F) all day and i know its to be hotter than that so dont want to go 1-7pm just to make sure i dont miss them. Would really prefer chilling more heading for there set and maybe a couple others but really cant do the 6 hours. Who is considered the headliners of the basscon pool party i assume theyd playe like 5-6? Any info would be appreciated.
