Date.prototype.setUTCHours()

The setUTCHours() method sets the hour for a specified date according to universal time, and returns the number of milliseconds since 1 January 1970 00:00:00 UTC until the time represented by the updated Date instance.

Syntax

dateObj.setUTCHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])

 参数

hoursValue
表示小时的整数,取值0到23之间。
minutesValue
可选参数。表示分钟的整数,取值0到59之间。
secondsValue
可选参数。表示秒数的整数,取值0到59之间。如果指定了该参数,就要同时指定 minutesValue这个参数。
msValue
可选参数。表示毫秒的整数,取值0到999之间。如果指定了该参数,就要指定 minutesValue和secondsValue这两个参数。

返回值

返回从1970-01-01 00:00:00 UTC 到更新后的日期所表示时间的毫秒数。

描述

If you do not specify the minutesValue, secondsValue, and msValue parameters, the values returned from the getUTCMilliseconds() methods are used.

If a parameter you specify is outside of the expected range, setUTCHours() attempts to update the date information in the Date object accordingly. For example, if you use 100 for secondsValue, the minutes will be incremented by 1 (minutesValue + 1), and 40 will be used for seconds.

例子

使用 setUTCHours()

var theBigDay = new Date();
theBigDay.setUTCHours(8);
