+I don't think it matters whether they are trivial or constexpr, because they
+cannot be used. Users only have access to `const time_zone` lvalues via
+`locate_zone` and the `tzdb::zones` container.
+The move constructor and move assignment operator only need to exist so that
+the implementation can populate that container.
