Hi DeltaYellow,
thanks for playing!
When you look at the room with the broken window, the goal is at the left end of the room.
To get there, go through the window, to the right, left and then you are in the center of the room (where you're stuck i guess). Look forward, maybe a bit to the left. Change the time and crouch forward next to a fire. You will find the terminal to the right.
I hope it helps! :)
