std::chrono::time_point<Clock,Duration>::operator+=, operator-= - cppreference.com (original) (raw)

time_point& operator+=( const duration& d ); (1) (since C++11) (constexpr since C++17)
time_point& operator-=( const duration& d ); (2) (since C++11) (constexpr since C++17)

Modifies the time point by the given duration.

  1. Applies the offset d to pt. Effectively, d is added to the internally stored duration _d_ as d_ += d.

  2. Applies the offset d to pt in negative direction. Effectively, d is subtracted from internally stored duration _d_ as d_ -= d.

[edit] Parameters

d - a time offset to apply

[edit] Return value

*this
