使用locale timeshift js从字符串解析日期

Question

我有一个字符串：“2014-01-22T09：44：06”

我想将它解析为同一个Date对象。这是我的工作：

var dateString = "2014-01-22T09:44:06";
var myDate = Date.parse(dateString);
console.log(new Date(myDate));

这是我得到的：

 Wed Jan 22 2014 13:44:06 GMT+0400 (Московское время (зима)) 

与原始字符串相比，日期对象移位4小时。如何消除这种转变？

获取时区偏移量：

您可以使用函数getTimezoneOffset()，它以分钟为单位返回您的时区偏移量：

var dateString = "2014-01-22T09:44:06";
var myDate = new Date(Date.parse(dateString));
console.log(myDate);
console.log(myDate.getTimezoneOffset());

在您的情况下，这将输出240

要获取UTC dateTime，您可以使用以下功能：

getUTCDate()           Returns the day of the month, according to universal time (from 1-31)
getUTCDay()            Returns the day of the week, according to universal time (from 0-6)
getUTCFullYear()       Returns the year, according to universal time (four digits)
getUTCHours()          Returns the hour, according to universal time (from 0-23)
getUTCMilliseconds()   Returns the milliseconds, according to universal time (from 0-999)
getUTCMinutes()        Returns the minutes, according to universal time (from 0-59)
getUTCMonth()          Returns the month, according to universal time (from 0-11)
getUTCSeconds()        Returns the seconds, according to universal time (from 0-59)
toUTCString()          Converts a Date object to a string, according to universal time

在您的情况下，您只需使用toUTCString()功能：

var dateString = "2014-01-22T09:44:06";
var myDate = new Date(Date.parse(dateString));
console.log(myDate);
console.log(myDate.toUTCString());
console.log(myDate.getTimezoneOffset());
