 > If you're setting the default to UTC early on, then resetting it later
 (for that 23/24ths of the world not in GMT time), then time() will give
 one answer at one point and a different answer later in the process. If
 anywhere you happen to compare the values from before and after that
 point, you're going to get weird results.

 time() need to be examined to see if they should be using gmtime()
 instead.

 It's quite early on:

 http://core.trac.wordpress.org/browser/trunk/wp-settings.php?rev=12315#L18

 one gets warnings if it's placed anywhere later. I do so your point,
 though. e.g. #9586...

 FWIW, I've been Ryan's two lines in the wp-config.php files of each of my
 sites for longer than I can remember. I also added it to my WP Fixes
 plugin, so that my customers can use it on their end. It *fixed* #9586 as
 a side effect, and I've yet to see reports of fishy sounding odd
 behaviors.
