Hello. I'm studying chronometry. I've been reading about NTP "time shift" attacks. I'm researching potential attacks that could be used in exploiting cryptocurrency transactions, among other exploits.
However, I'm finding it very difficult to find information about the NTP protocol hierarchy. Such as how many Stratum 0 devices exist? How many Stratum 1 devices? I know atomic clocks are in Colorado and CERN. But where else? There's about 20 atomic clocks listed on Wikipedia, but are they all connected to NTP?
I'm researching peer-to-peer synchronization, rather than a hierarchy structure. Because I'm interested in tracking the time dilation between peers, rather than synchronization. I want to write an application that tracks how much a system goes out of synch. I want to see if certain devices and certain activities cause greater time dilation, and why. Has anyone ever experimented with this?
For example, the clock in my car goes out of synch extremely fast. After about a month it will be as much as 1 minute our of synch. Whereas, my digital alarm clock goes out of synch much slower. At least it seems like it. Therefore the velocity of the car must be contributing to the increased time dilation. Therefore there must be a method to write an application that tracks this lag of time.
Can anybody point me to some references or other experts on the subject? Thanks so much.
