How to reset the date on nuvi 1300

Before I was able to get my nuvi 1300 to update software and maps, I purchased a used unit off of ebay, in case my device was broken.  The used unit has arrived, and I successfully updated the software and maps, after getting a new microSD card for it.  I can't find the setting now, but at one point I had a choice to see World Clock and World Map.  The date was September 16, 2006.  How I can re-set the date, or is it supposed to re-set automatically when it finds a satellite signal?  It finds a signal just fine.  I tried setting the Time by choosing Automatic, but that did not update either.  The minutes were right, but the hour was 1 hour slow.
