How to check if TDateTime option?

Question

I have an object that has one value, but this value can be either integer , string , boolean , or TDateTime . So this is Variant .

I use VarType() to check its type, but since VarType() does not have "varDate" or "varDateTime", I use "varDouble" because, as far as I can compile, TDateTime is double .

But this returns false. I also cannot use is to check for Variant TDateTime . Is there a way, or do I need to make some kind of type variable that determines what type this value is and use it to check?

Answer 1

Your assumptions are incorrect; actually there is varDate .
