The WP Super Cache plugin is finally playing well enough in my environment that I’ve been able to update from the ancient, abandoned WP-Cache plugin. I did notice however an issue with displaying dates in WordPress 2.8 and 2.8.1. The “Last” and “Next” Garbage Collection times are incorrect. Yet when I go to the WordPress Setting –> General page, the URC time and the Local Time are correct. It seems like the WP Super Cache plugin might be applying the UTC offset to the local time.
I don’t pretend that I have any clue what I’m doing, but making the following change in my wp-cache.php file fixed the issue, and now the times are displaying correctly.

That was it… just taking out a couple of tiny segments “+ ( get_option( ‘gmt_offset’ ) * 3600 ) ” from a couple of lines did the trick for me.
