js如何将时间戳转换成时间

let timestamp = 1633086000000; // 示例时间戳
let date = new Date(timestamp);
console.log(date.toString()); // 输出完整的日期和时间字符串

let timestamp = 1633086000000;
let date = new Date(timestamp);
console.log(date.toLocaleString()); // 输出本地化的日期和时间字符串

function formatDate(timestamp) {
    let date = new Date(timestamp);
    let year = date.getFullYear();
    let month = ('0' + (date.getMonth() + 1)).slice(-2); // 月份从0开始
    let day = ('0' + date.getDate()).slice(-2);
    let hours = ('0' + date.getHours()).slice(-2);
    let minutes = ('0' + date.getMinutes()).slice(-2);
    let seconds = ('0' + date.getSeconds()).slice(-2);

    return `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
}

let timestamp = 1633086000000;
console.log(formatDate(timestamp)); // 输出格式化的日期和时间

let timestamp = 1633086000000;
let date = new Date(timestamp);
console.log(date.toUTCString()); // 输出UTC时间字符串
