What do the times mean next to our posts? i.e. "4 min, 2 hours, 2 days" etc...
It is time elapsed since that message was posted ... but the time elapsed is not updated constantly (not every second), it is updated only every time new message is posted or deleted or edited ... if new message has not been posted during the last 1 month ... then time elapsed will be showing the time elapsed calculated 1 month ago ...
