[wp-hackers] peculiar problem on setting GMT

It should also be possible to display both the time relative to the post
author and the time relative to the viewing user. It could be as simple
as "17:30 IST (08:00 EST)" where IST is the author's time zone and the
user is viewing from EST. Assuming the query is changed to sort based on
post_date_gmt (which is should be), the author's time should be stored
in post_date, and is easily display (already), then detect users TZ via
JS and calculate from GMT and display both. As one of the options from a
theming standpoint, this gives users both sets of information: "What
time did s/he post this?" & "What time was it here when this was

WordPress stores both, actually. Local time in the post_date column
and GMT time in the post_date_gmt column.
However, the query system only uses the post_date, not the GMT version
of it. So yes, your ordering will be wrong with the current code.

That is a valid point, however you're limiting your audience
unnecessarily here, I think. Why only allow registered users to see it
in their time zone? If you're going to display time in the viewer's
time zone and adjust accordingly makes more sense. Then it works for
everybody, without any server side code really necessary.
The only reason I can see to have users have their own time zone is to
adjust the times of their posts to their local time, instead of to the
blog's local time. And that's perfectly fine and dandy, just don't
forget the ordering issues you'll have. This should be a relatively
simple fix though, just fix the order bit in wp-includes/query.php to
use post_date_gmt instead of post_date.
