[Boost-users] boost::date_time GMT/UTC question

Hello, Simple/quick question: is boost::posix_time::ptime boost::posix_time::second_clock::universal_time(), which is described as UTC in the boost manual page, equal to GMT? If not, what is the difference between UTC and GMT? As I understood it, UTC is the "new" name for GMT, but I'm not sure. Regards, Leon
