我遇到了一个问题，即我们的网络中主 DC PDC 模拟器无法获得正确的时间。它几乎一直处于 80 秒左右的关闭状态，我不知道如何修复它。
该机器现在是虚拟的（尽管我可以把它变成一个小的物理盒子）。w32 时间配置是：
PS c:\> w32tm /query /configuration

这表明延迟始终为 81-82 秒。同步不会改变这一点。
有人知道这是为什么吗？
根据要求，这里有更详细的状态：

这些是当前网络中的 3 台机器。请注意，名称中带有 ckg 的机器通过 VPN 距离约 170ms - 这是从中欧到芝加哥的时差。
答案1
完全禁用时间同步集成服务，我的意思是取消选中该框，这样它就不会提供给 Hyper-V 客户端。我知道这是很多人争论的焦点，甚至微软似乎也没有就此达成共识，但几年前我曾就此问题与微软有过支持案例，这就是他们建议的，从那以后我就再也没有遇到过问题。
启动时，您的虚拟机会从虚拟机管理程序获取时间（因为虚拟机没有实时时钟），此后它们应该只与域层次结构同步。对于 PDCe，它应该只与其配置的外部时间源同步。
