NTP通常可以在公共互联网保持几十毫秒的误差,并且在理想的局域网环境中可以实现超过1毫秒的精度。不对称路由和拥塞控制可能导致100毫秒(或更高)的误差。[2][3]

A time difference of less than 128ms between server and client is required to maintain NTP synchronization. The typical accuracy on the Internet ranges from about 5ms to 100ms, possibly varying with network delays. A survey by Professor David L. Mills suggests that 90% of the NTP servers have network delays below 100ms, and about 99% are synchronized within one second to the synchronization peer.
直连和走代理有什么区别?难不成走代理就无法同步时间了吗?或同步不准?
