No we dont. Because other genjutsu in the series such as ephemeral and the sharingan genjustu done on Bee have replicated similar effects and were fast according to you and we know for a fact that doesnt use time dilation. Black zetsu is the only third party reference in this scenario, and he thought that when sasuke initially was falling down that it meant sasuke lost the battle,  so he was referring to the fact that the overall battle was pretty short. You need to reread that panel more carefully. And like I said, zetsu showed a third party reaction to events that likely would have causee pain in sasukes real body, such as getting his eye ripped out in the illusion, meaning the genjutsu obviously wasnt instsnt, and thus didntnhave any meaningful time dilation. Even if it did, it would be on a much smaller scale than24-72 hours, and that's not likely to put anyone in a coma instantly
