How to get window open/creation date from window handle?

I have 2 MS Edge windows open in IE mode. I have to find out the one opened later. I have window handles for both. How can I do this? GetWindowInfo function does not return the open date. Is this possible? ChatGPT proposed some code but it didn't work

Here is a simple C# class to read creation date of a thread that opened a window specified by its handle. As Damien has warned below, thread creation and window open dates can differ.

using System;
using System.Runtime.InteropServices;

public class WindowCreationDateFinder
{
    [DllImport("user32.dll")]
    private static extern uint GetWindowThreadProcessId(IntPtr hWnd, out int lpdwProcessId);

    // Import the GetThreadTimes function from the kernel32.dll
    [DllImport("kernel32.dll")]
    private static extern bool GetThreadTimes(IntPtr hThread, out long lpCreationTime,
        out long lpExitTime, out long lpKernelTime, out long lpUserTime);

    [DllImport("kernel32.dll")]
    private static extern uint GetLastError();

    [DllImport("kernel32.dll")]
    private static extern IntPtr OpenThread(ThreadAccess dwDesiredAccess, bool bInheritHandle, uint dwThreadId);

    [DllImport("kernel32.dll")]
    private static extern bool CloseHandle(IntPtr hObject);

    [Flags]
    private enum ThreadAccess : int
    {
        QUERY_INFORMATION = 0x0040
    }

    public static DateTime GetWindowCreationDate(uint windowHandle)
    {
        var threadID = GetWindowThreadProcessId(new IntPtr(windowHandle), out _);

        if (threadID == 0)
            ThrowWinApiError("GetWindowThreadProcessId");

        IntPtr threadHandle = OpenThread(ThreadAccess.QUERY_INFORMATION, false, threadID);

        if (threadHandle == IntPtr.Zero)
            ThrowWinApiError("OpenThread");

        try
        {
            var b = GetThreadTimes(threadHandle, out long start, out long end, out long rawKernelTime, out long rawUserTime);

            if (!b)
                ThrowWinApiError("GetThreadTimes");

            return DateTime.FromFileTime(start);

        }
        finally
        {
            CloseHandle(threadHandle);
        }
    }

    private static void ThrowWinApiError(string funcCalled)
    {
        var m = $"{funcCalled} error: {GetLastError()}. See: https://learn.microsoft.com/en-us/windows/win32/debug/system-error-codes--0-499-";

        throw new Exception(m);
    }

}
