Thanks for the quick response!

 > [..] but we should start with the actual POSIX spec under TZ
Yes, that is exactly what I meant: Newlib supporting the <> (angle 
brackets) syntax.
I didn't know that it was actually part of POSIX spec, since so many 
libs actually don't implement it.

It looks like the TZcode implementation by Paul Eggert uses a different 
approach to parsing the strings, than the current implementation in 
newlib 
(https://sourceware.org/git/?p=newlib-cygwin.git;a=blob;f=newlib/libc/time/tzset_r.c). 
I'm not sure, if you want to copy the code over or use changes by e.g. 
Earle F. Philhower from 
https://github.com/earlephilhower/newlib-xtensa/pull/14.

Because of the above question, I'm not sure how to continue on this. I 
would like to contribute myself and submit an implementation, but I'll 
wait for feedback by other maintainers, first.
