Date.setUTCHours()

Sets the hour of a date object, according to universal time

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());
// expected output: Wed, 20 Aug 1975 23:15:30 GMT

Syntax

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

Parameters

hoursValueAn integer between 0 and 23, representing the hour.

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

secondsValueOptional. An integer between 0 and 59, representing the seconds. If you specify the secondsValue parameter, you must also specify the minutesValue.

msValueOptional. 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()

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