Ubuntu 22.04系统时钟偏移且NTP同步失效问题排查求助

大家好，我遇到了一个棘手的问题：我有一台正在同步BSC全节点的服务器，突然系统时钟偏移了2分钟，而且这个偏移还在缓慢增加。我想问问这会不会是硬件问题？

我的系统信息：

OS: Ubuntu 22.04.2 LTS x86_64

先贴一下timedatectl status的输出：

❯ timedatectl status

Local time: Sun 2023-04-09 16:29:58 UTC

Universal time: Sun 2023-04-09 16:29:58 UTC

RTC time: Sun 2023-04-09 16:29:58

Time zone: Etc/UTC (UTC, +0000)

System clock synchronized: yes

NTP service: active

RTC in local TZ: no

再看看systemd-timedated服务状态：

❯ sudo service systemd-timedated status                                                                                                                                                                                                                                                                       ─╯

我已经开启了系统时钟同步，而且NTP服务显示是活跃状态，但时钟还是不准。有没有大佬能教教我怎么调试这个问题？

我自己已经尝试过这些操作：

• 执行sudo ntpdate -s pool.ntp.org
• 重启NTP服务：sudo service ntp restart
• 重启服务器

下面是执行这些操作后的命令输出：

❯ sudo ntpdate ntp.ubuntu.com

9 Apr 16:52:50 ntpdate[3389]: step time server 185.125.190.56 offset +131.774604 sec

❯ date

Sun Apr  9 04:50:42 PM UTC 2023

UPDATE #

我发现时钟的偏移量在慢慢变大，以下是多次执行ntpdate的结果：

❯ sudo ntpdate ntp.ubuntu.com

9 Apr 16:52:50 ntpdate[3389]: step time server 185.125.190.56 offset +131.774604 sec
