概述

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

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;
