I'm just speculating here. If one has two time-like dimensions, it seems that one then really needs three such.

Speculate no more, you are entirely correct. Well done.

Thanks. I was just winging it.

Thank you so much for the heads up to the necessity for an odd number of time dimensions! This gives me something very engaging to research (the why of it) --- no hints, please - it "sticks" better if I figure it out on my own. Hugs!
