各ゲーム内通信メッセージのタイムスタンプをキャプチャして出力ウィンドウに表示するには、LuaコードのcaptureGameCommunications関数を次のように変更します：

```lua
-- Create a new output window with a given name
local outputWindow = createTextWindow("Game Communications", "Consolas", 12, 0, 0, 400, 300)

-- Define a function to capture all game communications and display them in the output window
function captureGameCommunications(event, message)
  if event == "comm" then
    -- Get the current time and format it as a timestamp string
    local time = os.date("%H:%M:%S")
    -- Append the timestamp and incoming message to the output window
    cecho(outputWindow, "<white>" .. time .. " " .. message .. "\n")
  end
end

-- Register the function to capture game communications
registerAnonymousEventHandler("comm", "captureGameCommunications")

```

ここでは、os.date関数を使用して現在時刻を取得し、"%H:%M:%S"(時:分:秒)のフォーマットでタイムスタンプ文字列として整形する。次に、cecho関数を使用して、タイムスタンプと受信メッセージを出力ウィンドウに追加します。
To capture and display timestamps for each in-game communication message in the output window, you can modify the captureGameCommunications function in the Lua code like this:

```lua
-- Create a new output window with a given name
local outputWindow = createTextWindow("Game Communications", "Consolas", 12, 0, 0, 400, 300)

-- Define a function to capture all game communications and display them in the output window
function captureGameCommunications(event, message)
  if event == "comm" then
    -- Get the current time and format it as a timestamp string
    local time = os.date("%H:%M:%S")
    -- Append the timestamp and incoming message to the output window
    cecho(outputWindow, "<white>" .. time .. " " .. message .. "\n")
  end
end

-- Register the function to capture game communications
registerAnonymousEventHandler("comm", "captureGameCommunications")

```

Here, the os.date function is used to get the current time and format it as a timestamp string with the format "%H:%M:%S" (hour:minute:second). Then, the timestamp and incoming message are appended to the output window using the cecho function.
