How can I stop an ingame leaderboard timer and put their time on a leaderboard?

I have an obby with an ingame timer, this comes from these two different scripts:

My question is, is there a way that when the character touches a block the timer can end and the time can be transferred onto a leaderboard of times on a billboard for the top ten.

(Like a time trial)

amount = 1
timedelay = 1
timename = "Seconds"

while true do
wait(timedelay)
for i,v in pairs(game.Players:GetPlayers()) do
if v:FindFirstChild("leaderstats") and v then
v.leaderstats[timename].Value = v.leaderstats[timename].Value + amount
end
end
end

game.Players.PlayerAdded:connect(function(plr)
local stats = Instance.new("BoolValue",plr)
stats.Name = "leaderstats"
local timer = Instance.new("IntValue",stats)
timer.Name = "Seconds"
timer.Value = 0
end)
