Missing Remote posted something a little different but perfect for their niche, a compendium of links to shared calendars in which you can find the broadcast times of every show on a wide variety of channels.  The links are either shared Google calendars or ICS links which are compatible with most calendar applications.  Never miss a TV show again, even if your guide is on the fritz or you are setting up a recording remotely.

"Missing Remote is proud to have many writers that are avid television watchers. When we were looking around for a list of shows and their start dates we found just those–list after list, so we have done the hard work for you and compiled these lists into shareable Google calendar with internet view or you can download and use it. Make sure you subscribe or come back, as we will be updating these all season. If you are like us and prefer to schedule only when it shows up on the guide, you will be watching this list daily when you can add your new shows up to 14 days in advance. We have made HTML links to look at the Google Calendar links and you can subscribe through that link, or ICS which is read by many of the popular desktop calendar applications, and you can subscribe to them through there"
