Hi everybody. My name is Axonn Echysttas and I'm a newbie to NTP. I'm currently working at developing a replacement for the Windows OS Systray clock. This program is free and I've been working on it for the past year a lot. It will enter Beta 2 no later than 25 January this year and Beta 3 (which will be public) probably during March this year. However, for the time being, even though I built a lot of functionality and it looks quite nice (very flexible and customizable), I didn't yet start on NTP time synchronization. I got the RFC about NTP and it scared me a little to see all those math formulae in it. On http://tf.nist.gov/service/its.htm I read that "The NIST servers listen for a NTP request on port 123, and respond by sending a udp/ip data packet in the NTP format. The data packet includes a 64-bit timestamp containing the time in UTC seconds since January 1, 1900 with a resolution of 200 ps."
My question is this: could you help me for a good cause? I would like to know how does the NTP format look like and how to take an accurate time out of it. I suppose I can always start reading and searching by myself, of course. But this thing doesn't look very easy at the first glance. Also, the amount of documentation on NTP seems huge. I don't know if the client-side NTP involves a lot of math but if it does, I'm not that good at math yet. I didn't yet graduate University and my school is on freeze for the last two years since I need to work to sustain my family. However, this project of mine I did in my free time and for the pleasure of doing something good and helping others, I will never request money for it. So how can I synchronize with a NTP server or more NTP servers? Is it so hard as I imagine after going a little through the FAQs? I would hope that the hard part is for servers, not for clients. I await your answers with great anticipation. Thank you very much for your time, Axonn Echysttas, ASD Clock creator. _______________________________________________ questions mailing list [email protected] https://lists.ntp.isc.org/mailman/listinfo/questions
