无法在 CentOS 7.3(1611) 上永久更改日期时间

我在云服务器上有CentOS7（1611）（中国腾讯提供），并尝试通过 , 更改date时间timedatectl。时间更改了，但是时间很快就自动更改为“实际当前时间”（有时更改时间后仅约1分钟就重置）。我关闭了 NTP 和 chronyd。顺便说一句，只有我可以访问服务器，其他人不能更改时间。

如何检查这个问题呢？或者有什么办法可以永久改变时间吗？

如果有任何信息遗漏，请告诉我。

我使用以下命令更改 CentOS 7 vicidial 服务器的时区：

# rm /etc/localtime
rm: remove regular file `/etc/localtime'? y
# ln -s /usr/share/zoneinfo/Europe/Rome localtime
# date

你会看到它已经改变了。
