Items consistently end up in my "Today" list before they are supposed to.

Today is 1/30. I just entered an item with a 2/2 due date. I specified that it should appear in "Today" one day before the due date, i.e. on 2/1. But there it is, the little pest, popping up in my "Today" list before I want to see it there.

Anyone else have a similar problem? Know whether I'm doing something wrong? Know about a fix?
