how to get ClockTime? What function can get ClockTime?

(I'm making AI script. when ClockTime is Under 6 or Over 17, They need to disappear. when I try to get ClockTime directly, only a time work.)

I'm trying to get Lighting.ClockTime but it doesn't get.

then, I'm going to try to get time with RemoteFunction.

--Server
wait(1)

while wait(1) do
	local ReplicatedStorage = game:GetService("ReplicatedStorage")
	local FunctionEvents = ReplicatedStorage.GiveClockTime
	for i,v in pairs(game.Players:GetChildren()) do
		local Time = FunctionEvents:InvokeClient()
	script.Parent.Parent.GlobalTime.Value = Time
	end
end

--Client
local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ClockRequest = ReplicatedStorage.GiveClockTime

local function OnInvokeTime()
	local Clock = game.Lighting.ClockTime
	return Clock
end

ClockRequest.OnClientInvoke = OnInvokeTime

but, Still, don't work. how should I use?

I finally know, I was changing value from studio, not script. sorry.
