posix_time是date_time中用于处理时间的库,时间功能位于名字空间boost::posix_time,需要包含的头文件为<boost/date_time/posix_time/posix_time.hpp>。首先看一下time_duration,它表述了时、分、秒的度量…
posix_time 使用 ptime 构造(参数为 date 和 time_duration 对象),另外可以用 time_from_string 和 form_iso_string 获得需要的 ptime 对象。通过 secondclock 和 microsecondclock 两个 namespace 下的 local_time 和 universal_time 可以获得当前时间; ...
