-# 时间时区子系统ChangeLog
-
-## cl.time.1 接口异常抛出变更
-
-时间时区子系统时间相关接口异常抛出：201权限否定异常、202非系统应用异常和401参数无效异常。
-
-**变更影响**
-
-基于此前版本开发的应用，继续使用无影响，使用新接口需要捕获并处理抛出的新异常。
-
-**关键接口/组件变更**
-
-变更前：
-  - 接口异常抛出message，错误码-1。
-
-变更后：
-  - 接口异常抛出message和code，包括201权限否定异常、202非系统应用异常和401参数无效异常。
-
-原接口中标记为废弃的接口，可以使用新接口中的同名接口替换
-
-| 原接口           | 新接口               |
-| ---------------- | -------------------- |
-| @ohos.systemTime | @ohos.systemDateTime |
-
-**适配指导**
-
-应用中调用systemTime所有接口可参考下列代码进行异常捕获，以setTime接口为例，其他接口适配方法相同。
-
-callback形式调用:
-
-**示例：**
-
-```js
-import systemDateTime from @ohos.systemDateTime
-// time对应的时间为2021-01-20 02:36:25
-let time = 1611081385000;
-try {
-    systemDateTime.setTime(time, (error) => {
-        //捕获权限否定异常和非系统应用异常
-        if (error) {
-            console.info(`Failed to setting time. message:${error.message}, code:${error.code}`);
-            return;
-        }
-        console.info(`Succeeded in setting time.`);
-    })
-} catch(e) {
-    //捕获参数校验失败异常
-    console.info(`Failed to set time. message:${e.message}, code:${e.code}`);
-}
-```
-
-promise形式调用：
-
-**示例：**
-
-```js
-import systemDateTime from @ohos.systemDateTime
-// time对应的时间为2021-01-20 02:36:25
-let time = 1611081385000;
-try {
-    systemDateTime.setTime(time).then(() => {
-    	console.info(`Succeeded in setting time.`);
-	}).catch((error) => {
-        //捕获权限否定异常和非系统应用异常
-    	console.info(`Failed to setting time. message:${error.message}, code:${error.code}`);
-	});
-} catch(e) {
-     //捕获参数校验失败异常
-    console.info(`Failed to set time. message:${e.message}, code:${e.code}`);

+## cl.time.2 接口异常抛出变更
+
+时间时区子系统时间相关接口异常抛出：201权限否定异常、202非系统应用异常和401参数无效异常。
+
+**变更影响**
+
+基于此前版本开发的应用，继续使用无影响，使用新接口需要捕获并处理抛出的新异常。
+
+**关键接口/组件变更**
+
+变更前：
+  - 接口异常抛出message，错误码-1。
+
+变更后：
+  - 接口异常抛出message和code，包括201权限否定异常、202非系统应用异常和401参数无效异常。
+
+原接口中标记为废弃的接口，可以使用新接口中的同名接口替换
+
+| 原接口       | 新接口         |
+| ---------------- | -------------------- |
+| @ohos.systemTime | @ohos.systemDateTime |
+
+**适配指导**
+
+应用中调用systemTime所有接口可参考下列代码进行异常捕获，以setTime接口为例，其他接口适配方法相同。
+
+callback形式调用:
+
+**示例：**
+
+```js
+import systemDateTime from @ohos.systemDateTime
+// time对应的时间为2021-01-20 02:36:25
+let time = 1611081385000;
+try {
+  systemDateTime.setTime(time, (error) => {
+    //捕获权限否定异常和非系统应用异常
+    if (error) {
+      console.info(`Failed to setting time. message: ${error.message}, code: ${error.code}`);
+      return;
     }
+    console.info(`Succeeded in setting time.`);
+  })
+} catch(e) {
+  //捕获参数校验失败异常
+  console.info(`Failed to set time. message: ${e.message}, code: ${e.code}`);
 }
