用于日期字段的特殊提示
When you enter a year using two digits, the corresponding four digit value is determined by a setting in LibreOffice - PreferencesTools - Options - LibreOffice - General. For example, if 1935 is set as the lower limiting value and you enter 34 as a date value, then the result is 2034 instead of 1934.
