"It has been usually interpreted to mean that the sun remained in the heavens twelve hours longer than usual. But this, though the most natural, is by no means the only interpretation of the p***age. The words, "did not hasten to go down as a perfect day," cannot be proved to have this meaning. In fact, it is difficult to fix a precise meaning on them. They belong rather to the domain of poetry than history, and their language is that of hyperbole rather than of exact narration of facts. Consequently, we are not en***led to build conclusions upon them, or draw arguments from them." http://biblehub.com/joshua/10-13.htm
Joshua 10:13 is pointing us do a different book to confirm ...so quote the other book to confirm if you feel strongly your views are the correct ones..
But from looking at the commentators I see that a lot of experts are not sure what the verse is saying...
From others I see the idea of the sun stopping is to be viewed in the same manner as when the Bible says Jesus is a door....he actually is not a door literally...
