From cppreference.com
< cpp‎ | chrono‎ | time point

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

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
