Does TrueTime Implement Based on RFC 5905 standard?

[yungkienpoh-prestolabs]

Hi,

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

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

1. Does TrueTime 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 TrueTime library use Network Time Protocol Version 4 or Simple Network Time Protocol (SNTP)?
3. How much is the precision of TrueTime in microseconds?
4. Anything else I should know when using the library but is not mentioned in the README or blog post?
