Windows10/11的时钟精度能够达到多少？

Hello

Thank you for posting in Microsoft Community forum!

Based on the description, I understand your question is related to C++.

Since there are no engineers dedicated to this topic in this forum, in order to be able to get a quick and effective handling of your issue, I recommend that you repost your question in Stack Overflow or Microsoft Q&A, they are designed for developers.

Thank you for your understanding and support. If you have any question or concern, please feel free to let us know.

Have a nice day!

Best Regards,

Wesley Li

感谢答复！

“如果能附上核心代码（C/C++）那最好了。”，可否暂时忽略这句话？

从系统性能或硬件角度，能否帮助解答一下？

因为我四处查，也查不到准确信息（包括微软客服电话），而项目又很急

谢谢！

Sorry, since this forum is not specifically targeted at engineers with a programming background, in order for your question to be addressed quickly and efficiently, I recommend that you republish your question in Stack Overflow or Microsoft Q&A, which are designed for developers.

感谢回复！

我在Microsoft Q&A上发布了，回复依然是让我查代码帮助文档，我很后悔提到函数名或编程这样的词汇。我想说，撇开代码不说，就没有人能真正说清或愿意说Windows能够达到什么级别的时钟精度吗？是不好意思吗？有什么不好意思的，Windows不是RTOS系统我知道，我的心理预期没那么高！唉...

Windows 中的时钟精度在最新版本中得到了显着提高。 在合理的操作条件下，运行 Windows 10 或 Windows Server 2016 及更新版本的系统可以配置为保持高精度。

对于 1 秒的精度，系统应该能够在正常操作条件下保持这一精度水平。

对于 50 毫秒 (ms) 的精度，系统应能够在正常操作条件下保持此精度水平。

为了达到 1 毫秒 (ms) 或更高的精度，系统应能够在合理的操作条件下相对于协调世界时 (UTC) 保持这一精度水平。

您可以通过与原子钟进行比较来检查系统时钟的准确性。 显示时间的准确度或精度为 0.02-0.10 秒，这取决于您的互联网连接和计算机的繁忙程度。
