Thansk! And sorry to see it so late.
There are several problems:

1. The installation of tzdata should be in the builder stage
2. If other time zones are specified through environment variables, can they take effect
3. The default time zone should be more international

Thanks for review

1. To support changing timezone by env, we should install tzdata in prod. This will provide us with all the necessary timezone data. They can take effect
2. As many of users are Chinese and i18n still in the todo list, I think it't better to set the default timezone to Asia/Shanghai

But you only copied the Asia/Shanghai time zone file to/etc/localtime. If specified other time zones through the environment variable, wouldn't the file be missing in/etc/localtime?

Both /etc/localtime and /etc/timezone are used to configure the current time zone of the system. Other files are stored in /usr/share/zoneinfo and will be read when specified.

I have tested it (here i use podman, the same to docker)

@1379 any updates on this? let me know if you have any questions

Sorry,I am too busy😭

Thanks
