我正在尝试设置 chrony，但它不起作用。我使用以下命令之一启动该服务：
sudo systemctl stop chronyd; sudo systemctl start chronyd
sudo systemctl restart chronyd
timedatectl 说我没有同步
timedatectl
Local time: Tue 2019-11-05 08:04:47 CET
Universal time: Tue 2019-11-05 07:04:47 UTC
RTC time: Tue 2019-11-05 07:04:47
Time zone: Europe/Zurich (CET, +0100)
System clock synchronized: no
NTP service: active
RTC in local TZ: no
不知何故，chrony 似乎无法解析我的源（我正在使用 Fedora 上提供的默认源）
chronyc activity
200 OK
0 sources online
0 sources offline
0 sources doing burst (return to online)
0 sources doing burst (return to offline)
1 sources with unknown address

我的配置文件（/etc/chrony.conf）

最奇怪的是，如果我停止守护进程并手动运行 chronyd 那么它就会起作用。
sudo /usr/sbin/chronyd -d -d > chronyd.out

我怀疑你现在已经解决了这个问题 - 但如果其他人也遇到同样的问题：
SELinux 会阻止来自 chronyd 的解析器访问，只需禁用它即可让您测试这是否是原因或添加异常。
