[Zope] Confusing DateTime().strftime behavior

I'm upgrading our server from a FoxPro backend to PostgreSQL, using the Psycopg connector. My problem is that the old database returned timestamps as a "%m/%d/%Y"-formatted string, while Psycopg returns a DateTime object (I'm using the internal module, not mxDateTime). Whenever I use strftime to format the object for display, I get the previous day's date instead. I've found several references to this problem in Google, but no one seems to have found a good solution. Any thoughts? -- Kirk Strauser The Day Companies
