Hello, i have lots of code using boost(1.33.1). It is a really great API. However, now I have to compile my code on a Solaris SPARC. I must use the Sun Compiler CC: Sun C++ 5.8 Patch 121017-10 2007/02/21. Using this compiler my code cannot be compiled. So, I've tested one of the date_time example(Simple Timezone) provided by your website: http://www.boost.org/doc/html/date_time/examples.html#date_time.examples .simple_time_zone I get the following error: "/export/home/venninj/opt/boost/1.33.1/include/boost-1_33_1/boost/date_t ime/posix_time/posix_time_io.hpp", line 189: Error: Could not find a match for std::has_facet<std::Facet>(std::locale) needed in boost::posix_time::operator<<<char, std::char_traits<char>>(std::ostream &, const boost::posix_time::time_duration&).
