Darksky api 未显示正确的时间

Question

我使用 Dark Sky API 变量 'time' 检索 unix 时间戳，然后使用以下代码将其转换为小时：

        if(navigator.geolocation){
            navigator.geolocation.getCurrentPosition(position => {
                long = position.coords.longitude;
                lat = position.coords.latitude;

                const proxy = "https://cors-anywhere.herokuapp.com/";
    const api = `${proxy}https://api.darksky.net/forecast/7fa728a1a158d84bf2c85bbeb53ddaea/36.778259,-119.417931`;

                fetch(api)
                    .then(response => {
                        return response.json();
                    })
                    .then(data => {
                        /*console.log(data);*/
                        const {temperature, summary, icon, time} = data.currently;

                                //Get date from time variable
                                var date = new Date(time*1000);
                                // Get hours from date
                                var hours = date.getHours();
                                // Get minutes from date
                                var minutes = "0" + date.getMinutes();
                                // Get seconds from date
                                var seconds = "0" + date.getSeconds();
                                // Display time in 10:30:23 format
                                var formattedTime = hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);

                                console.log(formattedTime);

                                //Check time
                                if (hours <= 19 && hours >= 7) {
                                //Day
                                } else {
                                //Night
                                }
});

其他一切工作正常，但它仍然没有在控制台中显示检索到的位置数据的正确时间。

根据the docs of Dark Sky API：

The API sends a response with a specific format，其中包含多个数据，但在这种情况下我们关心的是：

timezone (e.g. America/New_York) required

The IANA timezone name for the requested location. This is used for text summaries and for determining when hourly and daily data block objects begin.

Data Point Object

time required

The UNIX time at which this data point begins. minutely data point are always aligned to the top of the minute, hourly data point objects to the top of the hour, and daily data point objects to midnight of the day, all according to the local time zone.

所以你阅读的时间是机器UNIX time and this type of time is global time it is not for a specific time zone, so if you need displaying the correct time of the retrieved location you need to convert it to Locale Time by using toLocaleTimeString()在javascript

const proxy = "https://cors-anywhere.herokuapp.com/";
const api = `${proxy}https://api.darksky.net/forecast/7fa728a1a158d84bf2c85bbeb53ddaea/36.778259,-119.417931`;

fetch(api)
    .then(response => {
        return response.json();
    })
    .then(data => {
        /*console.log(data);*/
        const { temperature, summary, icon, time } = data.currently;
        //using data.timezone to displaying correct time of the retrieved location 
        //Get  time in 24 00:00:00 format
        var formattedTime = new Date(time * 1000).toLocaleTimeString("en-US", { timeZone: data.timezone, hour12: false });
        //Get  time in 12 00:00:00 AM/PM format
        var formattedTime = new Date(time * 1000).toLocaleTimeString("en-US", { timeZone: data.timezone });
        console.log(formattedTime);
    });
