How to run something every 60 seconds in Minetest

This is a quick note to show how to run something every 60 seconds(or less or more) in Minetest. What you want to use is globalstep. With minetest.register_globalstep(function(dtime)) you can run a function every step of the server which is usually 0.1

To achieve this goal, you need a variable to watch over time, decrease or increase it on every call of the globalstep and finally when it reaches some condition, execute the actual code. It will be something like:

local timer = 60

minetest.register_globalstep(function(dtime)
    timer = time - dtime
    if timer == 0.0 then
        minetest.chat_send_all("a minute has passed!")
	timer = 60
    end
end)
