Would an ORM have any way of determining that a SQLite column contains date-times or booleans?

I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types.

If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int?

If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not as bad as I fear. If you have any experience with this or a similar scenario, how did you handle it?
