[Zope] RE: "ZopeTime" not defined error?

Alright, I figured out that if I assign a user "Manager" rights, then my custom "login_form" works. However, it does *not* work if I go to my root Portal folder security tab and assign all rights to the "Member" role. So does the "manager" role have other instrinsic rights? Obviously I can't give everyone manager rights, just to work around this issue. If I stick the "login_form" in my "custom" skin folder, where would it be trying to access "ZopeTime" from that is different than the "generic" folder? And why does it think ZopeTime is not defined? --dave
