c++ - 将 tm 结构转换为 boost::local_time::local_date_time

Question

如何从 tm 时间结构创建一个 boost::local_time::local_date_time 对象？

Answer 1

有点痛苦，但看起来你必须通过 posix_time::ptime:

using namespace boost;
time_t rawtime;
time(&rawtime);
struct tm* timeinfo = localtime(&rawtime);
posix_time::ptime my_ptime = posix_time::ptime_from_tm(*timeinfo);
local_time::time_zone_ptr zone(new local_time::posix_time_zone("GMT"));
local_time::local_date_time my_ldt(my_ptime, zone);
std::cout << "local_date_time: " << my_ldt << std::endl;
