Date.prototype.getTimezoneOffset()

getTimezoneOffset() 方法返回协调世界时（UTC）相对于当前时区的时间差值，单位为分钟。

语法

dateObj.getTimezoneOffset()

参数

无

返回值

时区偏差（time-zone offset）表示协调世界时（UTC）与本地时区之间的差值，单位为分钟。需要注意的是如果本地时区晚于协调世界时，则该差值为正值，如果早于协调世界时则为负值。例如你所在时区为 UTC+10（澳大利亚东部标准时间），将会返回 -600。对于同一个时区，夏令时（Daylight Saving Time）将会改变这个值。

例子

例子： 使用getTimezoneOffset方法

var x = new Date();
var currentTimeZoneOffsetInHours = x.getTimezoneOffset() / 60;
