Redmine

I would love for our company to migrate from Trac to Redmine. I keep getting hung up on this part when migrating the postgresql database:

PGError: ERROR: timestamp out of range: "37328229-01-28 07:20:00.000000"
LINE 1: ...us_id", "author_id", "rgt") VALUES(NULL, NULL, 3, '37328229-...

I think it might be caused by a time.max (or something similar) entry that trac used in its postgresql database, although I am unsure. How can I get around this when I am migrating? It would be really unfortunate for this to end our process of trying to migrate to Redmine.
