Issue with the Event date/time selector in Chinese

Hi Team,

I found that when I my display language is not english (eg: Chinese Traditional), the AM / PM button is not working while selecting date/time in event. It also won't change while automatically while adding time from 10AM, 11AM.... 12PM , and it returns to 12AM in Chinese interface .

I guess is the problem for checking string of the date time value; in Chinese language it won't show AM/PM in the field but 上午(早上)/下午. Please advise anywhere I should fix this or I should force it only showing AM/PM?

Here attached is the screenshot FYR.

Thanks.
