(ec)Wait a minute, previously it was a "time zone" argument, but now it's a "likely to change at any time" argument? I'm hoping that you are cognisant of the fact that publications such as the World Almanac are printed volumes and are therefore likely to be picked up years after publication (when information is likely to have changed). In such cases, a disclaimer "as of" might be reasonable, but my experience in this part of WP is that there are a number of extremely diligent editors who will update information (often) minutes after events are confirmed. I'm willing to go along with "time zone" arguments but not with an argument that is trying to say that we should introduce text for the sake of the rare case where someone either dies or someone moves into the list and the list (and lede text) is not updated shortly after the event—which of course it always is.  ♬
