# @ohos.systemDateTime
The **systemDateTime** module provides system time and time zone features. You can use the APIs of this module to set and obtain the system time and time zone.
> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
## Modules to Import
```js
import systemDateTime from '@ohos.systemDateTime';
```
## systemDateTime.setTime
setTime(time : number, callback : AsyncCallback<void>) : void
Sets the system time. This API uses an asynchronous callback to return the result.

| callback | AsyncCallback<void> | Yes | Callback used to return the result.|
**Example**
```js
// Set the system time to 2021-01-20 02:36:25.
let time = 1611081385000;
try {
systemDateTime.setTime(time, (error) => {
if (error) {
console.info(`Failed to set time. message:${error.message}, code:${error.code}`);
