Even the latest Ubuntu systems still only have Shanghai in the "Time and Date Settings".
Yes, and when I click on Ürümqi the Ubuntu Time & Date selector highlights eastern Kazazhstan instead of any part of China (!). Also, Ubuntu's selector is still derived from old versions of tzdata that had unnecessary separate entries for Chongqing and Harbin and etc. And I'm sure it has other bugs. To get those bugs fixed the usual procedure is to file a bug report with the maintainers responsible. If that's something you want to do, I suggest filing a bug report against the Ubuntu timezonemap package and the GNOME gnome-control-center packages, as neither of these packages should be fooling around with Chongqing or Harbin nowadays. In your bug report please make it clear that this is not yet another "Change Asia/Shanghai to Asia/Beijing" bug report, Instead, I suggest saying that there are problems with the user interface in China regardless of what tzdata identifier denotes Chinese time. To improve the probability of a fix, it'd be helpful if your bug report included a patch. The PHP web page you mentioned merely lists tzdata identifiers including backwards links, and if that's the intent I don't see a bug there.
