为什么我的时间戳中的年份差了几个世纪？ PHP/Wordpress

Question

我在谷歌上搜索了很多，但一无所获，所以希望大家能提供帮助。

我称之为 API (https://api.metals.live/v1/spot). I'm converting the timestamp using PHP's date() function but I get back a date that is over 50,000 years in the future. I copied and pasted the same timestamp into this epoch converter (https://www.epochconverter.com)，它工作得很好。我也尝试过使用 WP 的内置 wp_date() 函数，未来还有 5 万年。

有人遇到过这个问题吗？

        $url = "https://api.metals.live/v1/spot";
        $response = file_get_contents('https://api.metals.live/v1/spot');
        //convert to PHP array
        $arr = json_decode($response,true);

        // Loop thru data and add it to new array
        $new_arr = [];
        foreach($arr as $x => $x_value) {
            foreach($x_value as $y => $y_value) {
                echo "Key=" . $y . ", Value=" . $y_value;
                echo "<br>";
                array_push($new_arr, (object)[
                    'metal' => $y,
                    'price' => $y_value
                ]);
            }
        }
        // print and format data in the array (for testing)
        foreach($new_arr as $x) {
            echo "<p>$x->metal : $x->price</p>" . "<br />";
        }

        // access gold price and convert to float
        $gold_price = floatval($new_arr[0]->price);
        // access silver price and convert to float
        $silver_price = floatval($new_arr[1]->price);
        //this is the timestamp value (despite it's name)
        $timestamp = $new_arr[4]->price;
        $date = date("Y-m-d H:i:s",$timestamp);
        echo $date;

Answer 1

时间戳 1638476352474 太长，因为它包含毫秒。将它除以 1000，您将得到一个正确的日期。

 $date = date("Y-m-d H:i:s",$timestamp/1000);
