js获取utc时间转换格式

// 获取当前UTC时间
let now = new Date();

// 获取UTC时间的年、月、日、小时、分钟、秒
let year = now.getUTCFullYear();
let month = now.getUTCMonth() + 1; // 月份从0开始，所以需要加1
let day = now.getUTCDate();
let hours = now.getUTCHours();
let minutes = now.getUTCMinutes();
let seconds = now.getUTCSeconds();

function formatUTCDate(date) {
    let year = date.getUTCFullYear();
    let month = (date.getUTCMonth() + 1).toString().padStart(2, '0'); // 补零
    let day = date.getUTCDate().toString().padStart(2, '0');
    let hours = date.getUTCHours().toString().padStart(2, '0');
    let minutes = date.getUTCMinutes().toString().padStart(2, '0');
    let seconds = date.getUTCSeconds().toString().padStart(2, '0');

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

let formattedDate = formatUTCDate(now);
console.log(formattedDate); // 输出格式如：2023-04-05 14:30:15

// 将UTC时间转换为本地时间
let localDate = new Date(now.getTime() + now.getTimezoneOffset() * 60000);
console.log(localDate.toLocaleString()); // 根据用户本地时区显示时间
