Unix 的tzset和 Windows 的_tzset只能全局设置时区,且对于如何设置程序到某一特定时区有不同的方法。 没有跨平台的高精度时间获取接口(Unix 下的gettimeofday不跨平台,在 Windows 上无法直接使用)。 没有跨平台的稳定时钟接口(性能测试需要;clock在 Unix 和 Windows 上具有不同的语义和精度)

In the Microsoft C++ implementation, `steady_clock::time_point` is now a `typedef` for `chrono::time_point<steady_clock>`. However, this isn't necessarily the case for other implementations. While the STL generally provides all features on all supported versions of Windows, leap seconds and...
boost::chrono::process_user_cpu_clock returns only the time spent running in user space. If a program is halted for a while, for example through the Windows Sleep() function, the time spent in Sleep() isn’t measured by boost::chrono::process_user_cpu_clock. Example 37.1 writes a str...
Edit & run on cpp.sh When you write distribution(generator) the distribution will use the generator as its source of randomness in order to generate a random number according to the distribution. No "seeding" is happening here. std::uniform_int_distribution tries to make all numbers within th...
