Each Time is special and requires extra setup. No, I don't remember what. I think an official level or two uses it, though.
I just went through all the single player levels, and the only ones who use Floor Touch + Each Time are CEZ2 and ERZ1. The effect is busted in both.
CEZ2 uses it for the little switches that change the water level in that one last room. All of the switches are on FOFs, except for one. The ones on FOFs work fine -- the water level changes only when the player touches the top of the FOF. The single one that works directly on the target sector is busted -- just going over it changes the water.
ERZ1 uses it for two purposes. In the first crusher room right after taking the left path, there are red and yellow crushers. The red ones are supposed to be activated simply by entering the sector. The yellow ones are supposed to require touching the floor. Both are triggered by just entering the sector.
The other place ERZ1 uses it is the part with the really quick floor crushers. Once again, supposed to activate on floor touch, just entering the sector will do.
If there's some weird way to make it work properly (other than always using FOFs), then the official levels' authors didn't know about it.
(Moreover, I'm pretty sure this combination worked fine in 1.09.4. Under such pressing evidence, I conclude that it might really be a bug.)
