Sure, maybe calling it a version of Tsukuyomi is inaccurate since each jutsu has different mechanics. IT is still the more potent genjutsu, though. Probably the most potent genjutsu seen in the series. And the only way you can break through it is via the Rinnegan or if you're an Edo (most likely because Edos don't have life force to suck on). So it would be pointless to bring up Tsukuyomi's time dilation when it's likely he won't get caught on it at all.

Let me remind you Itachi fought Nagato once and never used Tsukuyomi. You could say Nagato was an Edo and genjutsu doesn't work on them if Itachi hadn't been hit by Kotoamatsukami prior to that. He even went on to get hit by Kabuto's sound genjutsu and Sasuke's standard visual genjutsu.
