+# Device Settings Management
+
+The **EnterpriseDeviceManager** module provides capabilities to manage device settings, such as time settings. The APIs of this module can only be called by enterprise device administrator applications.
+
+> **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.
+
+## Usage
+
+Before calling any API in **EnterpriseDeviceManager**, use **getDeviceSettingsManager** to create an **EnterpriseDeviceManager** instance.
+
+```js
+import enterpriseDeviceManager from '@ohos.enterpriseDeviceManager'
+
+enterpriseDeviceManager.getDeviceSettingsManager((error, mgr) => {
+    if (error) {
+        console.log("error code:" + error.code + " error message:" + error.message);
+        return;
+    }
+    let deviceMgr = mgr;
+});
+```
+
+## DeviceSettingsManager.setDateTime
+
+setDateTime(admin: Want, time: number, callback: AsyncCallback<void>): void
+
+Sets the system time. This API uses an asynchronous callback to return the result.
+
+**Required permissions**: ohos.permission.EDM_MANAGE_DATETIME
+
+**System capability**: SystemCapability.Customization.EnterpriseDeviceManager
+
+**Parameters**
+
+| Name  | Type                                 | Mandatory  | Description     |
+| ----- | ----------------------------------- | ---- | ------- |
+| admin | [Want](js-apis-application-Want.md) | Yes   | Device administrator application.|
+| time  | number | Yes| Timestamp (ms).|
+| callback | AsyncCallback<void> | Yes| Callback used to the result. If the system time is set successfully, **err** is **null**; otherwise, **err** is an error object.|
+
+**Example**
+
+```js
+import enterpriseDeviceManager from '@ohos.enterpriseDeviceManager'
+
+let wantTemp = {
+    bundleName: "bundleName",
+    abilityName: "abilityName",
+};
+enterpriseDeviceManager.getDeviceSettingsManager((error, mgr) => {
+    if (error) {
+        console.log("error code:" + error.code + " error message:" + error.message);
+        return;
+    }
+    mgr.setDateTime(wantTemp, 1526003846000, (error) => {
+        if (error) {
+            console.log("error code:" + error.code + " error message:" + error.message);
+        }
+    });
+});
+```
+
+## DeviceSettingsManager.setDateTime
+
+setDateTime(admin: Want, time: number): Promise<void>
+
+Sets the system time. This API uses a promise to return the result.
+
+**Required permissions**: ohos.permission.EDM_MANAGE_DATETIME
+
+**System capability**: SystemCapability.Customization.EnterpriseDeviceManager
+
+**Parameters**
+
+| Name  | Type                                 | Mandatory  | Description     |
+| ----- | ----------------------------------- | ---- | ------- |
+| admin | [Want](js-apis-application-Want.md) | Yes   | Device administrator application.|
+| time  | number | Yes| Timestamp (ms).|
+
+**Return value**
+
+| Type  | Description                                 |
+| ----- | ----------------------------------- |
+| Promise<void> | Promise that returns no value.|
+
+
+**Example**
+
+```js
+import enterpriseDeviceManager from '@ohos.enterpriseDeviceManager'
+
+let wantTemp = {
+    bundleName: "bundleName",
+    abilityName: "abilityName",
+};
+enterpriseDeviceManager.getDeviceSettingsManager().then((mgr) => {
+    mgr.setDateTime(wantTemp, 1526003846000).then(() => {
+    }).catch((error) => {
+        console.log("error code:" + error.code + " error message:" + error.message);
+    })
+}).catch((error) => {
+    console.log("error code:" + error.code + " error message:" + error.message);
+})
+```
