backdating & use current time checkboxes?

Hello I've just started using both LJ and iJournal and am not sure where to look for documentation/info. My first question is about the 'Use current time' & 'backdated' checkboxes on the New Entry page of the OSX client. What exactly do these do? When do I want/need to use each checkbox? They sound like they should be mutually exclusive, but I haven't played around with it, I hope there's someone in the know who can tell me?
TIA
