The setUTCHours() method sets the hour for a specified date according to universal time, and returns the number of milliseconds since January 1, 1970 00:00:00 UTC until the time represented by the up
var event = new Date('August 19, 1975 23:15:30 GMT-3:00');
console.log(event.toUTCString());
// expected output: Wed, 20 Aug 1975 02:15:30 GMT
console.log(event.getUTCHours());
// expected output: 2
event.setUTCHours(23);
console.log(event.toUTCString());

Syntax
dateObj.setUTCHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])
Parameters
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
.
Return value
The number of milliseconds between January 1, 1970 00:00:00 UTC and the updated date.
Description
If you do not specify the minutesValue
, secondsValue
, and msValue
parameters, the values returned from the getUTCMinutes()
, getUTCSeconds()
, and 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.
Examples
Using setUTCHours()
setUTCHours()
var theBigDay = new Date();
theBigDay.setUTCHours(8);
