过去几个小时我一直在与 Chrony 作斗争，似乎无法弄清楚我做错了什么。我发现在 DNF 中尝试激活 Epel-release 时我的系统时间设置为 2015 年，一些证书错误导致我尝试解决时间日期问题。以下是我所有相关的输出：
# timedatectl
Local time: Wed 2021-05-05 16:24:27 EDT
Universal time: Wed 2021-05-05 20:24:27 UTC
RTC time: Wed 2021-05-05 20:24:27
Time zone: America/Detroit (EDT, -0400)
System clock synchronized: no
NTP service: active
RTC in local TZ: no
我必须手动设置时间，所以这实际上快了一分钟，以便我可以看到它是否正确运行。

从其他人的资料来看，这似乎不仅不切实际，而且是错误的

我甚至不确定从哪里开始解决这个问题，我尝试过运行和不运行防火墙。

我已经对我的配置文件进行了大量编辑，我的池可能有点奇怪，但我不确定还要将它们设置为何。在此之前，只有 1 个池指令被我愚蠢地删除而没有备份。
# ntpstat
unsynchronised
poll interval unknown
最后，在朋友的建议下，我使用了 ntpstat，它给了我这个输出..
我尝试过 chronyc makestep 和 refresh，但都没有结果
编辑：更新，我更改了配置，在适用的情况下包括“池”而不是“服务器”，看看是否能解决我的问题。没有成功
