I for one am happy to see progress made WRT time zone APIs in the C++ world.  cctz may not be entirely comprehensive (like the new Java 8 date/time api, etc.) , but it does what it does quite well.

Could be worse.  Could be like the Boost date_time api, which somehow thought it would be acceptable to map tzdb identifiers to fixed offset pairs, and never even bothered to keep them updated.http://www.boost.org/doc/libs/1_59_0/doc/html/date_time/local_time.html#date_time.local_time.tz_database
