I understand the idea but the facts are that visually this entrance is not well hidden at all. Anyway.
I should not be able to play the game for 2 hours without a single Long Rest and have the game transition to Day 2 without any shift from day to night and without using a Long Rest.
You could definitely be able to play the game for 2 real time hours without a single long rest IF exhaustion is not implemented (something I'd like a lot).
But you shouldn't have the transition to day 2 without any shift from day to night. I agree.
On the other hand I have to admit that at the moment, I just don't care about time in the log and I don't really understand anyone could care about because...
...Time doesn't mean anything in this game.
It should, but it doesn't.
Right now an accurate 1:1 time in the log wouldn't solve anything related to the lack of D/N cycle, the lack of exhaustion, the broken rest mechanic, the feeling of a static world etc...
I think it could even create more issues when things will be better implemented (whatever they are) and it would increase the feeling that the world is totally inconsistent.
