Comments in wrong order

Before I upgraded from Nagios 2.x to 3.0.6 all persistent host and service comments were sorted by date, with the newest at the top. After the upgrade the first new comment appears at the bottom of the stack and after that it seems almost random. Here is an sample of the Entry Time column of one host:

Entry Time
12-13-2008
07-09-2009
10-17-2007
04-01-2009

I would like to get the existing comments re-sorted correctly, and correct behavior going forward. Does anyone know how to fix this?
Thanks in advance.
