Twitter Tools Digest Time

I’m using Twitter Tools v. 2.2.1 to post a daily digest of my tweets to my blog. In my settings, I have the time set for the digest to post as 11:59pm (although I just changed it to 11:45pm). That worked fine up until I upgraded WordPress to version 2.9.1. Ever since the upgrade, my digest has been posting a 4:59am, five hours after it’s supposed to. It seems to be scheduling a digest post, labeling that post as “missed schedule”, then posting a replacement at 4:59am.

It’s not a huge deal, except that it’s listing the date of my tweets the day after they’re posted. Like I said, a minor annoyance, but an annoyance nonetheless.

I’ve already checked my Twitter Tools settings — they all seem to be correct. I checked the time on my blog, that is correct, as well. Anybody have an idea of why this might be happening or what I can do to fix it?

Thanks in adavance!

ETA: After a Google search on the problem, I discovered a previous post on these forums with a similar problem. But the successful fix is a version of the plugin older than the one I’m currently using.
