When you first take control of Jack, run around the right side of the pool building and use Time Vision to get onto the roof area near the front of the building, then run toward the "AWE" graffiti to find the collectible.
From the roof where you found the first chronon source, work your way back to the scaffolding above the trash bin where you climbed up, then jump for the higher scaffolding toward the back of the building (it looks too far to make it, but you'll see a yellow panel hanging down from the platform, which is this game's symbol for "the path Is over here"). Once on the platform, go through the hole in the roof to the attic, where the chronon source is.)
