I see. I thought T/Z meant "before this time" or "after this time" at first, but I get it now. Thank you.
Can you explain T and Z a bit here?
You are saying the _updateAt had to be before 2013-12-01 but at any time of the day?
Whereas "2013-12-01T12:00:00.000Z"
would be on any day before 2013-12-01 but after noon?
