使用jquery将字符串转换为UTC时间

var dateString = "2022-01-01T12:00:00";
var utcTime = Date.parse(dateString);

var utcDate = new Date(utcTime);

var year = utcDate.getUTCFullYear();
var month = utcDate.getUTCMonth() + 1; // 月份从0开始，需要加1
var day = utcDate.getUTCDate();
var hours = utcDate.getUTCHours();
var minutes = utcDate.getUTCMinutes();
var seconds = utcDate.getUTCSeconds();

if (month < 10) {
  month = "0" + month;
}
if (day < 10) {
  day = "0" + day;
}

var utcTimeString = year + "-" + month + "-" + day + " " + hours + ":" + minutes + ":" + seconds;
