It would say “1 day ago”. If it has been more than a month, it would still say “1 month ago”. In fact, sometimes in chat you can see messages with the icon “1 minute from now” or “seconds from now”. I asked ~-~WILL~-~ why this happens, and he said it was just how Questions2Answers registers posts posted before “seconds ago”. Also, if set the clock on your device behind, it will say “ 3 from now”, “3” being how much time your fake time is behind the real time.
