lua delay problem

mins = getMinutes() -- line 29
delay = mins + 10 -- 1 min == 1 sec IRL
if delay>60 then -- mins can never be bigger then 60 so a reduction can be needed.
    delay = delay - 60
end
while delay ~= mins do
    mins = getMinutes()
    if mins == delay then
        return false
    else
        print("wasn't equal")
    end
end
