So, if accuracy counts, what you're really saying is, for the show "Whodunnit?" www.imdb.com/title/tt2699226 three episode air dates are wrong (nothing really to do with Gildart Jackson, as Jackson's credits for the show are submitted to the show's page). Since it airs Sundays, episode #4, "Mountain Lyin'" would have aired July 14, not June, and episode #5 Bum-Ba-Dee-Da would have aired July 21, and episode 6, "All the World's A Stage" would have been July 28.
So, since all credits are submitted by users (and are sometimes wrong), there is, included on those two episode pages, yellow "edit page" buttons. You could correct it yourself and probably just give a link to the show's site that shows when it airs.
I'll submit it. Thanks for reporting (though I had to read it about 5 times before I could figure out what you were saying)!
