long story:
unfortunately you can't cause all containers are lightweight and will "share" the same linux kernel and setting the system time/date is a (privileged) kernel function.
this will work only inside a VM (vmware, kvm etc.) where's a full blown OS running it own kernel.
so you could start a docker container with "- - privileged=true" to manipulate the time/date inside this container.
but ... this will then afflect the hosts settings also, which means if you set a new time/date inside a privileged container it will modify the hosts time/date also and therefore set the time in all running containers to this new value.

启动容器时候加一下 -v /etc/localtime:/etc/localtime，容器里面就会跟host一个时区了
也可以在Dockerfile里面指定。

是不是from的基础镜像时间不对，在Dockerfile里面指定一下时区

建議在構建的時候可以加上一條指定時區的設置：
<pre>RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime</pre>

请问，如何修改容器时间，不是时区，是随意修改，类似date -s

应该不行，Time namespace没进入内核，所以没法隔离，找到一些更全面的解释：
short answer first: you can't

我觉得你应该还是想要修改时区就对了。
在Dockerfile里增加
<pre>RUN echo "Europe/London" > /etc/timezone; </pre>
就能更改系统成英国时区。
