The game by default does not give you the in-game timer. To unlock it, you must first have finished the game. After rolling the credits, you can find it under the stairs in the room with the clock. The timer can then be turned on in the settings. The timer is required to submit runs.

Have you thought of categories?

a number of categories have been suggested in the discord. some of the categories will include any%, all eggs, true ending, all bunnies, clock% / reach clock, etc. with sub categories between NMG and with Major Glitches. (2 different methods for wrong warping have been discovered so far)

You should probably include that it is located below the stairs in the room with the clock. Gotta grab it from the squirrel to unlock it.
