When creating/updating an datetime object in a date field is converted to the database datetime format. But when finding that entry with a datetime object won't return anything. You'll have to know how the database is storing the datetime value and then convert your datetime object. This is not the ORM-way of doing things, right? You should be able to create, update and find with the native datetime object and let the ORM-layer do the converting to specified database.
