There’s lots of documents out there on how to download the latest time zone data and apply it manually. In the interests of proper management though, I like using RPM to do pretty much everything. The problem is that Fedora Legacy has disbanded, so I can’t get patches for my FC1 and FC4 systems. The solution is to rebuild the FC6 packages and apply them to the legacy systems. (It’s entirely possible that they may apply directly since it’s noarch, but my local mirror didn’t seem to have the package)
