Message:

Correct how timezones are installed - this fixes various errors in test-suites. Thanks to Markku Pesonen for noting how Debian install timezones.

+          <filename class="directory">zoneinfo/posix</filename>. It is

+          <filename class="directory">zoneinfo</filename>, otherwise various
+          test-suites will report errors. On an embedded system, where space is
+          tight and you do not intend to ever update the timezones, you could save
+          1.9MB by not using the <filename class="directory">posix</filename>
