 If Mike’s response is typical, what he meant is only that dinner will be served close enough to six o’clock for current purposes. That would be typically be true if dinner will be served at 6:01. What Mike said, though, is that dinner will be served at 6:00, which would be false if dinner is served at  6:01.[21]  If Mike gave the same response to a question about when a swimmer touched the wall in the final lap of an Olympic event, 6:01 may not be close enough.
