Background
Our email vendor supports rss feeds for dynamic content, which we use successfully for "daily headline" type emails. This is a great help in automating many different emails that we don't have staffing to create daily. One of our staff as requested that his daily email (which has recent headlines from his Movable Type blog) only have headlines from entries posted on that day.
My Question
Since we use Movable Type for his blog, is there a way to generate a rss feed that only contains items posted on the current day?
Your solution can be simplified by using the "days" parameter on mt:Entries:
<?xml version="1.0" encoding="<$MTPublishCharset$>"?>
<feed xmlns="http://www.w3.org/2005/Atom">
<title><$MTBlogName remove_html="1" encode_xml="1"$></title>
<link rel="alternate" type="text/html" href="<$MTBlogURL encode_xml="1"$>" />
<link rel="self" type="application/atom+xml" href="<$MTBlogURL$>atom.xml" />
<id>tag:<$MTBlogHost exclude_port="1" encode_xml="1"$>,<$MTDate format="%Y"$>:<$MTBlogRelativeURL encode_xml="1"$>/<$MTBlogID$></id>
<link rel="service.post" type="application/atom+xml" href="<$MTCGIPath$><$MTAtomScript$>/weblog/blog_id=<$MTBlogID$>" title="<$MTBlogName encode_html="1"$>" />

No need for checking the date yourself, this also removes the empty "entry" tags your version creates.
