Accepted Agreements - Game Updates

So when a nomination is agreed upon to be added into a game (let’s say Pokémon go). I read somewhere in this forum that they’re updated into the game once a day.

Is there an exact time new nominations are added into the games daily or is that secret withheld information?

If not, what’s the UTC (-,+) time zone?
(I hope I structured this sentence correctly lol)

Wayspots are accepted into the shared database.

Any given wayspot may be used in a particular Niantic game depending upon criteria of that particular game (independent of which game was used to submit the wayspot).

For Ingress, it feels like roughly around around 5pm PT. I don’t know how it is actually implemented. But I imagine there is some processing involved in determining if there if “room” for new wayspots to be accepted as a portal in Ingress. Whether that is done before that magical time, then a single cut-over event, or if new ones are processed starting at that time and show up as they are approved (or removed, moved, etc).

Pogo sync should be rolling out NOW. I don’t have the times in UTC
