The constructor of boost::local_time::local_date_time expects its first parameter to be an object of type boost::posix_time::ptime and its second parameter to be an object of type boost::local_time::time_zone_ptr. boost::local_time::time_zone_ptr is a type of definition for boost:...

local_time(boost/date_time/local_time/local_time.hpp)提供了处理时区和本地化的基本功能; 另外通过 facet(C++ 对 locale 的支持)提供了多语言支持; boost.serialization 支持时间的串行化。 前面关于 boost.icl 的介绍里面我们也看到了部分 date_time 的应用,事实上 date_time 自己也提供了类似的功能。多数 ...
