Calendar AM/PM corrected for Chinese locale

When using the Chinese locale (zh_CN), opening a calendar control in the Report definition to select filter values resulted in the Calendar tab dropdown showing "上午" (AM) when the system time was in "下午" (PM). Investigation showed that when generating a non-auto date time control, ampm text (i.e. string value) was compared with the generated select component using locale specific values which did not match any time, so AM was always selected as it was the first value in the dropdown. To resolve this, the system has been updated to use the locale specific AM PM values for non-auto-generated date time control.
