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
[edit] Exceptions
May throw implementation-defined exceptions.
