Can someone tell me if this script works?

I have made a time script for my game, and sadly, my ROBLOX studio has stopped working. Could any of you see if this works?

while wait(0.4) do
	game.Lighting:SetMinutesAfterMidnight(GetMinutesAfterMidnight()+1)
	end

You did not point out where GetMinutesAfterMidnight was.

while wait(0.4) do
    game.Lighting:SetMinutesAfterMidnight(game.Lighting:GetMinutesAfterMidnight() + 1)
end
