[Zope] manage_main modification time

Our Zope installation has this really strange problem associated with the displayed "Modification Time" shown for each file in the /manage_main of a folder. The time that is shown is exactly one-hour later than the system time. I think I've tracked down this to the bobobase_modification_time variable. Both reference to <dtml-var "ZopeTime()"> and <dtml-var "_.DateTime()"> show the system time. <dtml-var "_.DateTime().timezone()"> shows US/Eastern. This is really not our correct timezone, since we are in West Lafayette, Indiana, which has it's own timezone: US/East-Indiana, but where does Zope/python get this from? Any ideas why bobobase_modification_time is off by one hour? --andy. Purdue Engineering Computer Network
