您好我正在使用getTimezoneOffset
并返回,例如-60
我如何为javascript设置全局时区偏移量?我试过了setTimezoneOffset('-120');
,但它没有用。我想在脚本开头全局设置它,以便稍后我可以简单地调用var d = new Date(); var n = d.getTimezoneOffset();
并返回我的值。请完全针对这种情况解决方案。谢谢!

Date.prototype.getTimezoneOffset = function () {return -120;};

我为你写这个polyfill(就像顶部) 最适合您的解决方案< 3 MY MYIEND!1
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(timezoneOffset) {
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:
Date.prototype.timezoneOffset = new Date().getTimezoneOffset()
Date.setTimezoneOffset = (timezoneOffset)->
return @prototype.timezoneOffset = timezoneOffset
Date.getTimezoneOffset = (timezoneOffset)->
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
