Restore Closest Key Version

local DataStoreService = game:GetService("DataStoreService")

local experienceStore = DataStoreService:GetDataStore("PlayerExperience")

local DATA_STORE_KEY = "User_1234"

local maxDate = DateTime.fromUniversalTime(year=2020, month=10, day=09, hour=01, min=42)

-- Get the version closest to the given time
local listSuccess, pages = pcall(function()
	return experienceStore:ListVersionsAsync(DATA_STORE_KEY, Enum.SortDirection.Descending, nil, maxDate.UnixTimestampMillis)
end)
if listSuccess then
	local items = pages:GetCurrentPage()
	if table.getn(items) > 0 then
		-- Read the closest version
		local closestEntry = items[1]
		local success, value, info = pcall(function()
			return experienceStore:GetVersionAsync(DATA_STORE_KEY, closestEntry.Version)
		end)
		-- Restore current value by overwriting with the closest version
		if success then
			local setOptions = Instance.new("DataStoreSetOptions")
			setOptions:SetMetadata(info:GetMetadata())
			experienceStore:SetAsync(DATA_STORE_KEY, value, nil, setOptions)
		end
	else
		-- No entries found
