formatter<std::chrono::year_month>

 

constexpr std::chrono::year_month& operator+=(const std::chrono::years& dy) const noexcept;	(1)	(since C++20)
constexpr std::chrono::year_month& operator+=(const std::chrono::months& dm) const noexcept;	(2)	(since C++20)
constexpr std::chrono::year_month& operator-=(const std::chrono::years& dy) const noexcept;	(3)	(since C++20)
constexpr std::chrono::year_month& operator-=(const std::chrono::months& dm) const noexcept;	(4)	(since C++20)

Modifies the time point *this represents by the duration dy or dm.

1) Equivalent to *this = *this + dy;

2) Equivalent to *this = *this + dm;

3) Equivalent to *this = *this - dy;

4) Equivalent to *this = *this - dm;

For durations that are convertible to both std::chrono::years and std::chrono::months, the years overloads (1,3) are preferred if the call would otherwise be ambiguous.
