It seems to be a limitation of the OutSystems platform that uses both Date and DateTime as datetime sql server data type, and thus, the limitation of 1753.
The only "easy" way I can think of to workaround this issue is to store your dates in a different forma (like text, for example), or like separate entities (year, month and day), that will help you with ordering and this kind of things.
You can see a discussion on the subject (but more focused on NULL), here.
