A coworker suggested filing a bug report, but I'm not confident enough in what I'm seeing to do so. I recently updated two servers from CentOS 5.2 to 5.4. In the process, of course, the tzdata package was updated. Shortly after updating, my boss began barking about a server with the wrong timezone showing up in our logging. He's very uptight about that sort of thing. We log everything with UTC religiously because we have servers all over the planet. Further investigation revealed that on these two particular servers, which had been updated with CentOS 5.4 (and the tzdata package), we could NOT change the time by the usual means (rm /etc/localtime; ln -s /usr/share/zoneinfo/UTC /etc/localtime). This works everywhere else in our datacenters, so we were confused. Upon looking closer, it appears the UTC file installed by the latest tzdata package is not a UTC file. Running strings on it reveals EST5EDT. I don't know if this is a problem at the source, or a packaging problem somewhere along the stream. I'm sending it to this email address because this is what I found in the README for the tzdata package. Please feel free to correct me in any way that will help me stop my boss from barking, as this is every information technologist's duty in life. Thank you for your brain cycles.
