Make threads that expire after "1 day" actually expire after 25 or 26 hours

Free users can currently set threads to expire after 24 hours (or less). This is a bit troublesome if you want to make a thread and send one message to it every day at the same time--unless you post earlier and earlier every day the thread will eventually archive itself. 

Making the 24 hour option be 25 hours instead (or perhaps 26 hours to account for DST) would solve this issue.
