Hour/Min/Sec - systeme, how to correctly make ?

I make a "Happy New Years Simulator" and i must created a television with date and hour/min/sec, for the date, it ok, but for the Hour/Min/Sec, i have a some worries, can you help me for fix this?

Script1 - No Error

local Min = script.Parent.Min
local Sec = script.Parent.Sec


while wait(1) do
	Sec.Value = Sec.Value+1
	if Sec.Value > 59 then
		Min.Value = Min.Value +1
		Sec.Value = 0
	end
end

Script2 - No Error

local Hour = script.Parent.Hour
local Min = script.Parent.Min
local Sec = script.Parent.Sec


while wait() do
	if Min.Value and Sec.Value < 10 then
		script.Parent.Text = Hour.Value..":0"..Min.Value..":0"..Sec.Value
	elseif Sec.Value > 10 then
		script.Parent.Text = Hour.Value..":0"..Min.Value..":"..Sec.Value
	elseif Min.Value and Sec.Value > 10 then
		script.Parent.Text = Hour.Value..":"..Min.Value..":0"..Sec.Value
	end
end

it has no error, just it not work correctly

Err this is kind of difficult, but you should be doing something like this. You should just do like minutes and seconds b/c thats when the real countdown starts. but here :

function secondstotimer(seconds)
	local minutes = math.floor(seconds / 60)
	local remainingseconds = seconds % 60
	if remainingseconds <= 0 then
	remainingseconds = "00"
	elseif remainingseconds <= 9 then
		remainingseconds = "0" .. tostring(remainingseconds)
		else
		 remainingseconds = tostring(remainingseconds)
		end
	return tostring(minutes) ..":" .. remainingseconds
end

I'm just kind of guessing cuz idk rlly know where u put ur gui and stuff but err u can just use this for reference and go from there. hope it helps!
