Compares two time points. The comparison is done by comparing the results time_since_epoch() for the time points.

1-2) Checks if the time points lhs and rhs refer to the same time point for the given clock.
3-6) Compares the time points lhs and rhs.

Contents

Parameters

lhs, rhs - time points to compare

Return value

1) true if the lhs and rhs refer to the same time point, false otherwise.
2) true if the lhs and rhs refer to different time points, false otherwise.
3) true if the lhs refers to time point before rhs, false otherwise.
4) true if the lhs refers to time point before rhs, or to the same time point as rhs, false otherwise.
5) true if the lhs refers to time point after rhs, false otherwise.
6) true if the lhs refers to time point after rhs, or to the same time point as rhs, false otherwise.

Exceptions

(none)

Notes

These operators were not constexpr in C++11, this was corrected in C++14
