Looks like this logic is not well understood by the communities.
The same thing for PHP: http://php.net/manual/en/timezones.asia.php
It's better if you could add the "Asia/Beijing" identifier.
Thanks!

Similarly, if you look at the time zone settings dialog program published by the
tz project, you'll see "Beijing Time", not "Shanghai Time". Please see the
shell transcript at the end of this message.
The string 'Asia/Shanghai' is a tzdata-specific identifier, not intended to be
visible to non-experts. It's like 'America/New_York' (which is not the string
that a non-expert user would expect in Washington DC) or 'Asia/Kolkata'
(likewise for a non-expert in New Delhi). If you're selecting time zones via a
user interface that's showing the string "Shanghai Time", I suggest writing to
whoever's maintaining that user interface (it's not us :-).
$ tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent, ocean, "coord", or "TZ".
1) Africa
2) Americas
3) Antarctica
4) Asia
5) Atlantic Ocean
6) Australia
7) Europe
8) Indian Ocean
9) Pacific Ocean
10) coord - I want to use geographical coordinates.
11) TZ - I want to specify the time zone using the Posix TZ format.
