std::chrono::time_zone

成员函数

time_zone::name

time_zone::get_info

time_zone::to_sys

time_zone::to_local

非成员函数

operator==operator<=>

 

在标头 <chrono> 定义
bool operator==( const std::chrono::time_zone& x,                  const std::chrono::time_zone& y ) noexcept;	(1)	(C++20 起)
std::strong_ordering operator<=>( const std::chrono::time_zone& x,                                   const std::chrono::time_zone& y ) noexcept;	(2)	(C++20 起)

以名称比较两个 time_zone 值 x 与 y。

<、<=、>、>= 及 != 运算符分别从 operator<=> 与 operator== 合成。

返回值

1) x.name() == y.name()

2) x.name() <=> y.name()
