		(2)
time_point& operator-=( const duration& d );				(until C++17)
constexpr time_point& operator-=( const duration& d );				(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.

Parameters

d

-

a time offset to apply

Return value

*this.

Exceptions

(none)
