How can I make a command block emit a redstone signal after 20 mins. I want it to emit a redstone signal after 20 mins to power another command block that will have /tp to send all players to a certain area. It will also need some thing that resets it to 20 mins
Best Answer
You will actually need to build a redstone timer that takes 20 minutes to output a signal. There was a recommendation for a /wait command, however, it was not implemented. There are plenty of delay timer designs you can look in to though. I have also included a link to the official commands list.

Answer 2
The easiest way to accomplish this is to have a command block summon an Item entity with an age of minus 15 minutes on top of a pressure plate on a block on which a redstone torch is attached to.
The item will despawn in 20 minutes, depowering the block and turning the redstone torch on.
