C-style date and time

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 .

a time offset to apply
