For Chinese (zh), use 12-hour formats with day periods

Description

There has been some discussion related to time formats for Chinese - whether to use 12-hour formats using "ah" or 24-hour formats with "HH". My uderstanding is that the actual preference is for 12-hour formats with day periods, e.g. "Bh" or "hB" (to produce the equivalent of "7:00 in the morning", "3:00 in the afternoon", "8:00 at night") , but we do not make clear that that is now an option.

Make it more clear that this is an option, determine whether that is actually the preference, update formats accordingly.

I’ve also filed before. Glad that it finally has been fixed for zh-cn. Thanks Peter for collecting feedbacks and making the change.

Just let me add the reason why the 24-hour clock should be preferred for CN.

According to CN's current national standards (GB/T 7408-2005 (sorry for only Chinese version available), which is equivalent to the ISO international standard: ISO 8601:2000 and ISO 8601:2004, titled Data elements and interchange formats — Information interchange — Representation of dates and times), local time should be based upon the 24-hour timekeeping system. New ISO standard ISO 8601-1:2019, revised ISO 8601:2004, also says "times based on the 24-hour clock", and this standard is also a recommendation in CN.

Actually with further feedback, the resolution is that HK and MO should use ah:mm regardless of script/language.

Feedback (from translators/localizers/internationalQA) is:

  • For CN, strongly prefer 24-hour time, HH:mm. Many many examples provided to suggest that this now the most common form for times in text (though not necessarily in informal speech), I can attach these later.

  • For TW, consistent preference for 12-hour with day periods, e.g. Bh:mm. Several examples provided.

  • For HK, feedback is quite mixed; some prefer Bhmm, others HH:mm, others say 12-hour is consistent with e.g. Hong Kong Observatory.
