The DATE_CMD variable was found to be very limited,
so I replaced it with a new variable called
DATE_FORMAT. This requires a change in blog.conf, so
replace DATE_CMD=`date '+%B %d, %Y %r'` with
DATE_FORMAT="%B %d, %Y %r" (or similar line). This
will hopefully resolve the difficulties that came up when trying to
change an entry's date format.
