Err TimerServicesStartup (int32 delta_priority)
The service thread doesn't use many CPU cycles, and it uses them only when you make requests for services and when time events occur. Generally, you should run the service thread at a slightly higher priority than the rest of your tasks/threads, especially if timely notifications are critical.
If this function returns positive 1, that indicates that someone else has already started the service thread. In this case, you should respond by calling TimerServicesOpen()
to connect with the already-running thread.
