I have an RHEL4 server with no connectivity to Internet. (Of course, I can scp files into that server from my network). RHEL4 is out of support and RedHat no longer releases tzdata update RPMs for it. At least, I couldn't find an update RPM from RedHat.
My server runs Java 6u20. Is there a way to update the tzdata files using, let's say the timezone files provided at http://mm.icann.org/pipermail/tz-announce/2018-January/000048.html? Or any other mechanisms to update tzdata? Basically I need to get the latest DST info into that server.
