The WP Options timezone is set correctly. The GMT time zone is set correctly. I'm on the west coast (california). the offset to GMT is set correctly (-8). All of the time stamps are appearing correctly on my site for months. However, it seems like WP still uses a few things based on the server's local clock (east coast, 3 hours ahead, -5 from GMT).
When I select to show only 3 days of entries, the last day expires exactly 9 o clock. Also I use Jennifer's plugin: http://www.scriptygoddess.com/archives/2004/06/20/today-in-weeksmonthsyears-past/#more-1279
This plugin lets me show a post from exactly one year ago, one month ago, or one week ago. The link to that post expires exactly 9pm as well, which is again based on the server's local clock (east coast). Is there a way to fix this?
