@ottorino: you are right that the current scheduler is centered around the concept of ‘start times’ during each day, and ignores start times that fall onto the next day or previous day. It’s definitely possible to address this limitation by extending the search computation. But in the end it’s not as flexible as a general calendar. We may need to re-think about how to implement the scheduler to accommodate more flexible programming. If anyone has a good idea, feel free to speak up. Thanks.
