I am re-establishing my site as a WordPress blog instead of Movable Type. As you can see from that link, I'm having a few problems. I have done a few test imports before I import the 5000 old entries in bulk.
Of the five entries I imported today, two of them show up as December 31st, 1969. I cannot figure out why some of them import the correct date just fine and the others are screwing up. The dates look properly-formatted. I can't import my posts until I can resolve this issue.
Does anyone know how to prevent the 1969 date problem? This appears to be my last major issue, so if I can resolve this then I can get my site relaunched.
