我在笔记本电脑上运行 Ubuntu 20.04。自安装以来，我从未遇到过日期/时间不同步的问题。
但是今天当我启动笔记本电脑时，系统时间完全错误。我可以禁用 NTP 并手动设置正确的时间，但当我重新启用 NTP 时，时间又回到错误状态：
david@david-XPS-15-9570 ~ timedatectl
Local time: Mo 2021-10-04 08:20:36 CEST
Universal time: Mo 2021-10-04 06:20:36 UTC
RTC time: Mo 2021-10-04 06:20:37
Time zone: Europe/Vienna (CEST, +0200)
System clock synchronized: no
NTP service: inactive
RTC in local TZ: no
david@david-XPS-15-9570 ~ sudo timedatectl set-ntp on
david@david-XPS-15-9570 ~ timedatectl
Local time: Mo 2038-10-04 07:52:04 CEST
Universal time: Mo 2038-10-04 05:52:04 UTC
RTC time: Mo 2021-10-04 06:21:14
Time zone: Europe/Vienna (CEST, +0200)
System clock synchronized: no
NTP service: active
RTC in local TZ: no
- 我已经重启了笔记本电脑多次，只是为了确保
- 我检查了 BIOS 中的日期和时间 - 它们是正确的
知道这里发生什么事了吗？
附加信息：
AFAICT，NTP 应该正在查询ntp.ubuntu.com

...根据https://servertest.online/ntp应该没事...

我将配置文件中的行更改为这些值
NTP=pool.ntp.org
NTP=pool.ntp.org
NTP=ntp.ubuntu.com
但没有什么区别……
