This is broken: -f expectes exactly one argument and you're giving it anexpression that expands to multiple arguments.

================

but, why would it work on bsd and not work on solaris?

The [ ... ] form of tests isn't recommended anyway, because thearguments aren't parsed properly so this sort of error will be hidden.But it's not at all clear what you're trying to do. I think you'relooking to see if at least one of the files in the expansion exists, inwhich case try expanding the expression and using a null glob:
files=(/usr/{share,lib,share/lib}/{zoneinfo,locale/TZ}/${TZ}(N))
if (( ${#files} )); then
 # stuff
fi

================

very slightly modified, and working great...

 local tz_file
 tz_file=(/usr/{share,lib,share/lib}/{zoneinfo,locale/TZ}/${TZ}(.N))
 (( ${#tz_file} )) || export TZ=Etc/UTC

thanks!
