Thread:Help talk:Type Date/How to change date format in property page?

I would like to ask whether the date format in the property page could be changed. For example, in the property page of a DateType property, pages using this property in the list are automatically arranged by date. But the date displayed is always in the day-month-year format (e.g. 30 December 2013 23:59:25). I would like to know how to change it into year-month-day format. I have tried to search for solutions in this wiki but it seems that there is no related content.
