in-game timer shows 9:36 because the timer breaks when playing on 30 fps. I started time when the first room loads and ended time when the player left the last room.

Mod note: In-game time ends when screen becomes black after final cutscene, as you can easily find out by timing this way the other 60 FPS runs, playing at 30 FPS means the in-game time is exactly double as it should be, so 9:36 / 2 is 4:48 to compare with 60 FPS runs.
