句法

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

参数

hoursValue

An integer between 0 and 23, representing the hour.

minutesValue

Optional. An integer between 0 and 59, representing the minutes.

secondsValue
Optional. An integer between 0 and 59, representing the seconds. If you specify the secondsValue parameter, you must also specify the minutesValue .
msValue
Optional. A number between 0 and 999, representing the milliseconds. If you specify the msValue parameter, you must also specify the minutesValue and secondsValue .

返回值

The number of milliseconds between January 1, 1970 00:00:00 UTC and the updated date.

描述

If you do not specify the minutesValue , secondsValue ,和 msValue parameters, the values returned from the getUTCMinutes() , getUTCSeconds() ,和 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.
