Disclaimers: this source might be outdated - also forgot how I initially found these, if anyone has a more recent source do let me know. I also might not have understood some of wording correctly. And lastly, some of these timers are impossible in a normal gameplay (no way to destroy goalzones before 9:00 or something)

The most important timers to note here are 8:50 (main goal of the center lane pokemon should be helping one of their lanes secure the altaria exp), 7:20 is not as commonly known so you can sneakily prepare to secure it with your lanemate. 3:15/3:00 is also not as known but it's the last lane altarias that will spawn before 2:00

Source of the information is Unite DB

The transparent ones are the ones where the item is listed as an optional item (or just mentioned in the build's description)
