415, 462 - wiki time
Hi. Here's an FYI re Simmons wikis from David Dwiggins, in response to the question "Why are the times associated with the changes made to the wiki incorrect?"
It appears that MediaWiki is designed to keep all times internally in GMT, and there is no easy way to change this globally. However, individual users can change their own time zone preferences by clicking on "Preferences" and then "Time Zone." From there they can enter "-4" to subtract 4 hours to get the right time for Easter Daylight time. I think it would need to change to -5 during the winter.
Not a perfect solution, but should work.
