+## cl.time.1 接口异常抛出变更
+
+时间时区子系统定时器接口异常抛出：202非系统应用异常和401参数无效异常。
+
+**变更影响**
+
+该接口变更前向兼容，基于此前版本开发的应用可继续使用接口，增加相应的异常处理，原有功能不受影响。
+
+**关键接口/组件变更**
+
+变更前：
+  - 接口异常抛出message，无错误码。
+
+变更后：
+  - 接口异常抛出message和code，包括202非系统应用异常和401参数无效异常。

+**适配指导**
+
+应用中调用systemTimer所有接口可参考下列代码进行异常捕获
+
+createTimer callback形式调用：
+
+**示例：**
+
+```js
+export default {
+    systemTimer () {
+        let options = {
+            type: systemTimer.TIMER_TYPE_REALTIME,
+            repeat: false
+        };
+        try {
+            systemTimer.createTimer(options, (error, data) => {
+                if (error) {
+                    //捕获权限否定异常
+                    console.info(`Failed to create timer. message:${error.message}, code:${error.code}`);
+                }
+        	});
+        } catch(e) {
+            //捕获参数校验失败异常
+            console.info(`Failed to create timer. message:${e.message}, code:${e.code}`);
+        }
+    }
+}
+```

+
+**示例：**
+
+```js
