# Date.setUTCMilliseconds()
The setUTCMilliseconds() method sets the milliseconds for a specified date according to universal time.
```javascript
var date1 = new Date('2018-01-24T12:38:29.069Z');
console.log(date1.getUTCMilliseconds());
// expected output: 69
date1.setUTCMilliseconds(420);
console.log(date1.getUTCMilliseconds());
// expected output: 420
```
## Syntax
```javascript
dateObj.setUTCMilliseconds(millisecondsValue)
```
#### Parameters
`millisecondsValue`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 a parameter you specify is outside of the expected range, `setUTCMilliseconds()`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 1100 for `millisecondsValue`, the seconds stored in the [`Date`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) object will be incremented by 1, and 100 will be used for milliseconds.
## Examples
#### Using `setUTCMilliseconds()`
```javascript
var theBigDay = new Date();
theBigDay.setUTCMilliseconds(500);
```
