My intention was to create a plugin to allow authors to set their own time zones. It shouldn’t take too much, but I keep having to put it off. It just needs to take into account daylight savings time, but this is a little tricky because you need to keep a record somehow of past DST times for posts published in the past.
I have a couple ideas for implementing this, but if anyone else has any brilliant ideas, please go for it. Another thing I intend to do is hook into <code>pre_option_gmt_offset</code> instead of the <code>get_the_time</code> filter, as it does now.
Let me know of any problems: jj56@indiana.edu

This plugin represents a RSS feed separator, which enables your readers to create RSS subscriptions that only contain posts with specific tags. 
For example, visitor A could create and subscribe to an RSS feed including the tags cooking, recipes, and fine living. Visitor B, could 
instead prefer to read posts related to the tags cocktails, wine, and night life. Each person will have it’s own RSS Feed URL, and each of 
those feeds will only include posts that have one or more of the preselected tags.
If you have a busy blog with lots of entries in it, you should definitely consider installing Selected Tags RSS, in order to enable your visitors 
to subscribe just to the topics they are interested in.
You can configure the location where the the RSS selector would be showing from the plugin settings. If your theme supports widgets you can add and configure a widget from Appearance > Widgets > Selected Tags RSS.
The plugin supports shortcodes. Use <code>[selected-tags-rss-post title="***"]</code> shortcode to show RSS link in posts and <code>[selected-tags-rss-search title="***"]</code> to show the RSS Selector. Title parameter is the optional name of link.
