My question is rather simple and has to do with the extra-dimensional space* created by a Rope Trick spell.
*Note: It is not clear to me whether this kind of space is a Demiplane or not, but should any solid source clarifying this also help with the actual question, it will be welcomed.
I would like to know how exactly time works in the aforementioned space. SRD describes 4 different ways for time to operate in a given plane: Normal, Timeless, Flowing and Erratic.
However I am not aware which one of these applies for a given demiplane or where I can find rules defining that. Any official sources would be appreciated.

Well, Rope Trick descriptions reads as follow:
Well, what is an "extradimensional space" then?
Then, let's look at the planes that might have a different Time Flow:
So, the only way for a Rope Trick to have a different Time Flow would be to belong to the Astral Plane, Limbo, or Plane of Time (obviously not the case), or to be a Demiplane.
However, as mentioned above, the extradimensional space created by a Rope Trick is specifically described as "outside the multiverse". And when we look at what the Planes are:
So the Demiplanes belong to the Multiverse. A Rope Trick extradimensional space is outside of the Multiverse. (a short but interesting thread on the issue)
And if there were still a possibility that Rope Trick was considered as linking to a Demiplane (which would open an awful can of worms), you can just rely on the following:
So as a conclusion:
