The Podcast module does not sort podcasts when displayed from view.php. When records are retrieved from the database (lib.php near line 448) the optional 4th argument to get_records() is not used to specify a sort field.

Additionally, in the database table podcast_structure, there is no field that stores the date and time of posting in a sortable format.

Ideally, I would like the sort order to be either by posting date and then by title, or by posting date and time.

I've hacked my installation to sort by name, and then added the date to the start of the title.
