Rss feed from Calendar

This is not a huge deal, but I am noticing the RSS feed from the calendar, while to truncating expired events from the top of the list , adds them to the bottom. This is not the case in the right hand event display on the forum home page.

Look at this forum

The calendar function is adapted to provide another function other than the calendar. Anyway you can see events on the right that are outdated do not appear.

Now look at this site which receives an RSS feed from it. If you scroll down the tight hand list, you will notice it is receiving expired events at the bottom.
