Does Kronos Implement Based on RFC 5905 standard? #109

Hi,

My team is considering to use Kronos for our financial application.

However, I have a few questions before I can make a decision:

1. Does Kronos library fully implements based on the NTP latest standard (RFC 5905)? If not, can you share the document that you implement based on?
2. Does Kronos library use Network Time Protocol Version 4 or Simple Network Time Protocol (SNTP)?
3. How much is the precision of Kronos in microseconds? is it 15.625 microseconds? Is it possible to adjust for higher precision?
4. Anything else I should know when using the library but is not mentioned in the README or blog post?
