Yeah I get that but I don't know what that means.
however after some reading I have discovered a few things:
The reason the DB Multiverse consists of hyper timelines is due to the entire multiverse being one timeline, and there being several other "timelines" within a given universe, those being the Hyperbolic Time Chamber and the Pendulum Room. However these are founded based on complete BS.
First of all the Hyperbolic Time Chamber is supposedly as big as the world as stated by Goku in the Cell Saga, which of course is vague because it could either mean the universe or it could mean the planet. However every official translation of this phrase quotes it as being the size of the earth or planet. Furthermore, the method that the Time Chambers' time flow is different is specifically referred to as "time dilation" and the different Time Chambers have different rates of slowing time (as seen in the Moro Arc). This implies that things in the Time Chamber just move faster than normal, and exiting the chamber slows you back down. If that is too outlandish, we can still break it down to "we don't know if the Time Chamber(s) are actual other dimensions or just pocket dimensions the size of planets". This is further proven in Super when Vegeta destroys the Time Chamber, and is in the location of where the Chamber once was, and NOT somewhere outside of Universe 7.
Second of all, the Pendulum Room thing is complete BS, if not completely swept under the rug, like many things established in OGDB. We can tell that the Pendulum Room does not create time for the rest of the universe because it was destroyed in the Buu Saga. If it was destroyed, there should be no time. Also, unlike the Hyperbolic Time Chamber, the Time Room is actually located inside Kami's Lookout, unlike the Hyperbolic Time Chamber, which would have just had its entrance destroyed. This is also very disproven in DBH, as it's stated that Tokitoki's eggs create the time for a universe. Not the Pendulum Room.
Neither of those spaces are really what they claim they are, and as such, the cosmology should be 2-C for canon, 2-A for DBH.
