如何编写非别名的std::chrono::high_resolution时钟类模板专门化

template<typename Duration>
class MyHighResolutionClock {
public:
    using rep = typename Duration::rep;
    using period = typename Duration::period;
    using duration = Duration;
    using time_point = std::chrono::time_point<MyHighResolutionClock, duration>;

    static constexpr bool is_steady = /* 根据实际情况设置是否稳定 */;
    
    static time_point now() noexcept {
        /* 实现获取当前时间点的代码 */
    }
};

#include <iostream>
#include <chrono>

template<typename Duration>
class MyHighResolutionClock {
public:
    using rep = typename Duration::rep;
    using period = typename Duration::period;
    using duration = Duration;
    using time_point = std::chrono::time_point<MyHighResolutionClock, duration>;

    static constexpr bool is_steady = /* 根据实际情况设置是否稳定 */;
    
    static time_point now() noexcept {
        /* 实现获取当前时间点的代码 */
        return time_point(duration(/* 获取当前时间的代码 */));
    }
};

int main() {
    using MyClock = MyHighResolutionClock<std::chrono::nanoseconds>;
    MyClock::time_point start = MyClock::now();
    
    // 执行需要测量时间的代码
    
    MyClock::time_point end = MyClock::now();
    MyClock::duration duration = end - start;
    
    std::cout << "Time elapsed: " << duration.count() << " nanoseconds" << std::endl;
    
    return 0;
}
