The year of "民國" is 100 now, but the date field only displays two digits for "00". How to reproduce? Step 1. Insert > Fields > Date Step 2. Double click the date inserted Step 3. Choose which example shows "88/12/31" or "民國88年12月31日" Step 4. The date will changed to something "00/12/31" or "民國00年12月31日" Expectation: The "00" should be "100" now, and not to restrict the digits.
Plus, Calc has the same problem, too.
Important information: You should use "Chinese (traditional)" for Locale setting first. Go to Tools > Options > Language Settings > Languages to set them.
Programs using the "Date" funciotion in "Chinese (tradtional)" locale might all be affected.
