Tetris DS only has a timer on VS play though. In singleplayer mode, you can spin until your thumbs get tired of spinning, just like Tetris Worlds.I think Tetris DS had a timer where if you rotated continuously while the piece was on the floor it would lock down after 8 seconds. If you can't place a piece after 8 seconds you're doomed anyway. For 8 seconds or infinity, if you can continuously rotate the piece for a long period of time without penalty, it takes away from the core of the game massively.
Tetris DS is the only one I've played that had such a timer anyhow. I don't live in Japan, so Arika ports don't affect me.
Every official Tetris Company game after that (Splash, Party, Friends, and Axis) had a fairly short timer (something like 5 spins or 2 seconds).
Also, there's a number of Tetris clones that faithfully recreate the Arika games. A lot of people consider the Arika games to be the best games for speedrunning Tetris, so it might be worth giving a try.
