This is just one process on the system. It has to get a timeslice to notice that the timer has expired and then it has to finish whatever else it is doing (like reading received packets and processing their contents before it sees that it needs to send a packet. Naturally this cannot happen instantaneously. I'm not sure why you are insistant on this or why it's so important to have it sent at the exact moment. It doesn't matter to NTP, so why does it matter to you? The packet is timestamped when it goes out and not when the timer expires. Can you explain what it is you are concerned about and why this is so important to you? You don't get any better accuracy.
