创建一个带有设置时区的日期，而不使用字符串表示

我有一个网页，有三个下拉菜单，分别是日、月和年。如果我使用JavaScript Date构造函数接受数字，那么我得到一个Date对象为我的当前时区:

new Date(xiYear, xiMonth, xiDate)

给出正确的日期，但由于夏令时，它认为日期是GMT+01:00。

这里的问题是，然后我将这个日期传递给一个Ajax方法，当日期在服务器上被反序列化时，它已经转换为GMT，因此失去了一个小时，这将一天往回移动了一个小时。 现在我可以将日、月和年分别传递到Ajax方法中，但似乎应该有更好的方法。

接受的答案为我指明了正确的方向，但是仅仅使用setUTCHours()本身就改变了:

Apr 5th 00:00 GMT+01:00

to

Apr 4th 23:00 GMT+01:00

然后，我还必须设置UTC日期、月份和年份

Apr 5th 01:00 GMT+01:00

这正是我想要的

当前回答

这是最好的解决方案

使用:

// TO ALL dates
Date.timezoneOffset(-240) // +4 UTC

// Override offset only for THIS date
new Date().timezoneOffset(-180) // +3 UTC

代码:

Date.prototype.timezoneOffset = new Date().getTimezoneOffset();

Date.setTimezoneOffset = function(timezoneOffset) {
  return this.prototype.timezoneOffset = timezoneOffset;
};

Date.getTimezoneOffset = function() {
  return this.prototype.timezoneOffset;
};

Date.prototype.setTimezoneOffset = function(timezoneOffset) {
  return this.timezoneOffset = timezoneOffset;
};

Date.prototype.getTimezoneOffset = function() {
  return this.timezoneOffset;
};

Date.prototype.toString = function() {
  var offsetDate, offsetTime;
  offsetTime = this.timezoneOffset * 60 * 1000;
  offsetDate = new Date(this.getTime() - offsetTime);
  return offsetDate.toUTCString();
};

['Milliseconds', 'Seconds', 'Minutes', 'Hours', 'Date', 'Month', 'FullYear', 'Year', 'Day'].forEach((function(_this) {
  return function(key) {
    Date.prototype["get" + key] = function() {
      var offsetDate, offsetTime;
      offsetTime = this.timezoneOffset * 60 * 1000;
      offsetDate = new Date(this.getTime() - offsetTime);
      return offsetDate["getUTC" + key]();
    };
    return Date.prototype["set" + key] = function(value) {
      var offsetDate, offsetTime, time;
      offsetTime = this.timezoneOffset * 60 * 1000;
      offsetDate = new Date(this.getTime() - offsetTime);
      offsetDate["setUTC" + key](value);
      time = offsetDate.getTime() + offsetTime;
      this.setTime(time);
      return time;
    };
  };
})(this));

咖啡版本:

Date.prototype.timezoneOffset = new Date().getTimezoneOffset()


Date.setTimezoneOffset = (timezoneOffset)->
    return @prototype.timezoneOffset = timezoneOffset


Date.getTimezoneOffset = ->
    return @prototype.timezoneOffset


Date.prototype.setTimezoneOffset = (timezoneOffset)->
    return @timezoneOffset = timezoneOffset


Date.prototype.getTimezoneOffset = ->
    return @timezoneOffset


Date.prototype.toString = ->
    offsetTime = @timezoneOffset * 60 * 1000
    offsetDate = new Date(@getTime() - offsetTime)
    return offsetDate.toUTCString()


[
    'Milliseconds', 'Seconds', 'Minutes', 'Hours',
    'Date', 'Month', 'FullYear', 'Year', 'Day'
]
.forEach (key)=>
    Date.prototype["get#{key}"] = ->
        offsetTime = @timezoneOffset * 60 * 1000
        offsetDate = new Date(@getTime() - offsetTime)
        return offsetDate["getUTC#{key}"]()

    Date.prototype["set#{key}"] = (value)->
        offsetTime = @timezoneOffset * 60 * 1000
        offsetDate = new Date(@getTime() - offsetTime)
        offsetDate["setUTC#{key}"](value)
        time = offsetDate.getTime() + offsetTime
        @setTime(time)
        return time

其他回答

使用. settutchours()可以实际设置utc时间的日期，这将允许您在整个系统中使用utc时间。

但是不能在构造函数中使用UTC设置它，除非指定日期字符串。

使用新的日期(日期。UTC(年，月，日，小时，分，秒))，您可以从特定的UTC时间创建一个日期对象。

当我创建一个日期对象:

日期(年、月、日、时、分)

我在本地主机上工作得很好。 当我部署到服务器时，它崩溃了，因为服务器在另一个时区。

我不能使用getTimezoneOffset()。我需要我的家的时区偏移-取决于夏季/冬季时间

// add diff minutes between myself (HOME) and server 
timezoneHomeOffset (d, tz = 'Europe/Copenhagen') {
  const utc = new Date(d.getTime())
  const dHome = new Date(d.toLocaleString('en-US', { timeZone: tz }))
  const diff = Math.round((utc - dHome) / 60000) // 60*1000 => minutes
  d.setMinutes(d.getMinutes() + diff)
  return d
}

简单地设置时区和返回根据

new Date().toLocaleString("en-US", {timeZone: "America/New_York"})

其他时区如下
