Correct me if I'm wrong (or have missed something) but events described in Far Beyond the Stars episode, seen from DS9 perspective seems to be lasting a single day.
It also seems, that in the beginning of the episode, Joseph Sisko welcomes his son and grandson and in the end of episode he seems to be quickly saying goodbye.
How can that be or what am I missing? From this answer we can learn that the Defiant needs at least 10-11 days to travel between DS9 and Earth, so any regular transportation ship will take this for let's say at least half a month.
Should we assume that Joseph Sisko spent an entire month traveling to see his son and grandson for a total of a single day? Where am I lost here?
