Well, when we start the episode it's the Hell Week evaluation on the Saturday night and I don't think we get any specific time, but it's probably around 9 or 10 at night. The next day the MC does a bit of yoga with Bella and Jill then has breakfast with them and can optionally go see M&J after that. When he arrives at the DIK mansion it's still sunny so it's probably around midday or early afternoon at that point.
The summary screen is the MC in the "library" with his DIK jacket at night, and maybe this is an indication he spent the rest of the day there, but in terms of the action we saw unfold it's probably around 12-16 hours of in-game time.
No official announcements and won't get one until they know for sure, but best guesstimates from people here is October.
If you want to catch up on what's been released so far, you can take a look at this:
We're certainly locked in to the Major Choices that take those blocks away, but the smaller decisions that decide status do not appear to be locked in at all and even if you've knocked off the "Massive" portion of the affinity bar, you can still be a Massive DIK or CHICK, so it doesn't really seem to have an affect on how high the MC's status can go.
Honestly, we've had many discussions here about how this status/affinity system has issues because aside from locking the player out of certain scenes and relationships, it doesn't create quite as much control over him as a character or his personality as people think, and is really just a convoluted way of creating replayability even if what you get locked out of doesn't often make much sense.
