Just to note, I added a couple transclusions of {{show by date}} to dated statements related to the premiere. The template will switch from "set to premiere" to "premiered" at precisely 0:00 UTC, March 20, which is 8pm New York March 19, which is precisely when the premiere begins :) Jujutaculartalk 08:02, 18 March 2011 (UTC)[reply]
