Wait, no.  I found it.  %m is the month, %e is the day, and %Y is the year, so I can use format="%m-%e-%Y" to get 12-18-2001.

I don't see how to format the date to display the NUMBER of the month of the entry instead of a word of abbreviated word for it's name.  Is there some easy way to do this that I'm just overlooking?

For instance, if I want "12-18-2001" instead of "December 18, 2001" there is no way (I can see) to do so.
