std C库提供了一个跨平台的方法来获取当前日期和时间在C ++中？ a href =http://en.cppreference.com/w/cpp/chrono/c/time =noreferrer> time（） 。
这是从时代开始的秒数，可以使用标准C函数转换为日期和 H：M：S 。 Boost 还有时间/日期库，你可以检查。

  time_t timev; 
时间（& timev）; 
 

Is there a cross-platform way to get the current date and time in C++?

std C libraries provide time(). This is seconds from the epoch and can be converted to date and H:M:S using standard C functions. Boost also has a time/date library that you can check.

time_t  timev;
time(&timev);
