It seems like the "Iv'e checked all these" button updates the time from the user's local machine. This may lead to wrong results as if this button is pressed after few other messages have been posted elsewhere, they will not be seen by the user.
To avoid the race condition, the button should change the time to the time of the last message that was sent to the user on this node
(in other words, if this was an OS issue, it would crash)

Just a thought.
