# Date.setUTCSeconds()
The setUTCSeconds() method sets the seconds for a specified date according to universal time.
```javascript
var date1 = new Date('December 31, 1975, 23:15:30 GMT+11:00');
console.log(date1.getUTCSeconds());
// expected output: 30
date1.setUTCSeconds(39);
console.log(date1.getUTCSeconds());
// expected output: 39
```
## Syntax
```javascript
dateObj.setUTCSeconds(secondsValue[, msValue])
```
#### Parameters
`secondsValue`An integer between 0 and 59, representing the seconds.
`msValue`Optional. A number between 0 and 999, representing the milliseconds.
**Return value**
The number of milliseconds between 1 January 1970 00:00:00 UTC and the updated date.
## Description
If you do not specify the `msValue` parameter, the value returned from the [`getUTCMilliseconds()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/getUTCMilliseconds) method is used.
If a parameter you specify is outside of the expected range, `setUTCSeconds()` attempts to update the date information in the [`Date`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) object accordingly. For example, if you use 100 for `secondsValue`, the minutes stored in the [`Date`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) object will be incremented by 1, and 40 will be used for seconds.
## Examples
#### Using `setUTCSeconds()`
```javascript
var theBigDay = new Date();
theBigDay.setUTCSeconds(20);
```
