比较两个时间点。通过比较结果进行了比较。time_since_epoch()时间点。
1-2%29检查时间点lhs和rhs请参考给定时钟的相同时间点。
3-6%29比较时间点lhs和rhs...
参数
| lhs, rhs | - | time points to compare |
|---|
返回值
1%29true如果lhs和rhs参考同一时间点，false否则。
2%29true如果lhs和rhs参考不同的时间点，false否则。
3%29true如果lhs指时间点以前rhs，，，false否则。
4%29true如果lhs指时间点以前rhs，或者在同一时间点rhs，，，false否则。
5%29true如果lhs指时间点后rhs，，，false否则。
6%29true如果lhs指时间点后rhs，或者在同一时间点rhs，，，false否则。
例外
%280%29
注记
这些经营者不是constexpr在C++11中，这一点在C++14中得到了纠正。
