使用此JavaScript将本地时间转换为另一个时区

var localDate = new Date();

var timezoneOffset = localDate.getTimezoneOffset();

var targetOffset = 480; // 假设目标时区为东八区（北京时间）
var targetTime = localDate.getTime() + (timezoneOffset + targetOffset) * 60000;
var targetDate = new Date(targetTime);

var targetYear = targetDate.getFullYear();
var targetMonth = targetDate.getMonth() + 1; // 月份从0开始，需要加1
var targetDay = targetDate.getDate();
var targetHour = targetDate.getHours();
var targetMinute = targetDate.getMinutes();
var targetSecond = targetDate.getSeconds();
