You could use the OpenProcess (see [1]) and similar Win32 API methods, which are
to some extent accessible through Mark Hammonds Win32 wrappers:

    import win32api
    import win32process

    PROCESS_QUERY_INFORMATION = 0x0400

    pid = win32api.GetCurrentProcessId()
    h = win32api.OpenProcess(PROCESS_QUERY_INFORMATION, False, pid)

    print win32process.GetProcessTimes(h)
