That manual is out of date, and documents only up through tzdb version 2. You're 
looking at a version 3 file. I sent a bug report to mtk.manpages at gmail.com 
suggesting that they update their copy of the man page. Also, I spruced up the 
tzdb man page as described here:

This should make it easier for their project to simply copy the upstream file.

That TZ setting works for me, if I set the TZ environment variable to it. I am 
using Fedora 26, which uses glibc 2.25. By mentioning "/etc/TZ" I suspect you 
are using some other C library. Which C library and version number is it? We can 
send its maintainers a bug report.
