As I wrote above that can only be a workaround hack. Changing such
kind of files inline is a source of race conditions and program
crashes, not a solution.

Not if it points to a file in /usr/share/zoneinfo/... You don't want
to change the contents of the target file, but you want to change the
symlink itself to a new target. But the latter again doesn't work on
an r/o file system, so we'd need some intermediate file like
/etc/localtime → /data/localtime → /usr/share/zoneinfo/...
