This question already has an answer here:
I have recently found that my MC world does not auto-save (Don't answer on how to do that), so I have to /save-all every 5 minutes or so.
However, I have created a timer hooked up to a /save-all command block. Note that all repeaters are set to max delay.
Basically, what happens is, there is a redstone signal passing through the repeaters. When it reaches the end, it hits out a command block and loops around back to the starting which goes through the timer again.
I have timed this as 2:24.
Is there a much efficient design to the timer or any part of the structure?
Is there also a way to increase the time without changing a major part of it?
Please don't suggest any latchology as I am terrible at it.
