I just went straight to the paper. The article appears to misrepresent the proposed dimensions of time by attempting to analogize with 3D space.
What is actually proposes is a fundamental difference between classical physics and quantum physics and how the two are unified across an intersecting dimension, which gives rise to cause and effect. It does not appear to inherently support or oppose the many worlds interpretation, as the article implies.
t1 - mass (quantum-scale time)
t2 - cause/effect (interactions between t1 & t3)
t3 - gravity (cosmological-scale time)
