将时间同步至毫秒精度和机器间精度的最佳方法是什么？ [英] What's the best way to synchronize times to millisecond accuracy AND precision between machines?

问题描述

据我所知，PC上的晶体对于时钟偏移而言是臭名昭着的。如果时钟始终偏斜，那么以毫秒级精度和精度同步机器之间时钟的最佳方法是什么？从我发现的，NTP和PTP是可能的解决方案，但我想知道是否有人在stackoverflow.com上有任何经验！

据我所知，NTP是流行的选择，但是我想知道是否有人使用过PTP（IEEE1588）解决方案

它可以选择从几个GPS设备接收输入信号，也可以与网络服务器通信。

编辑：我是指的是 http://www.ntp.org/ ，而不是Windows附带的。

对于哪些NTP客户端最适合windows，我没有任何建议，但对于Unix机器，没有真正的理由不运行NTP。

From what I understand, the crystals on PC's are notorious for clock skew. If clocks are always skewing, what is the best way to synchronize clocks between machines with millisecond accuracy and precision? From what I've found, NTP and PTP are possible solutions, but I was wondering if anybody had any experience on stackoverflow.com!

I understand NTP is the popular choice, but am wondering if anybody has had any experience with PTP (IEEE1588)

解决方案

Just run the standard NTP daemon.

It does have options to take input from several GPS devices as well as talking to network servers.

Edit: I was referring to http://www.ntp.org/, not the one that comes with Windows.

I don't have any suggestion as to what NTP clients are best for windows, but for Unix machines there's no real reason to not run NTP.
