* The %Timer class can activate the timer and notify the listeners.
- * Once the target goes into sleep mode, Timer does not work properly because the main loop gets stopped.
- * You can use Alarm on behalf of Timer for sleep mode.
+ * It supports the relative time and provides both repeatable and non-repeatable timers.
+ * Because %Timer is handled in an event-driven way, when the main loop gets blocked, even if the time is expired, the listener cannot get notified.
+ * Once the target goes into the sleep mode, %Timer does not work properly because the main loop gets stopped.
+ * You can use Alarm on behalf of the %Timer for the sleep mode.
* For more information on the class features, see <a href="../org.tizen.native.appprogramming/html/guide/base/timer.htm">Timer</a>.
* The following example demonstrates how to use the %Timer class.
*
* @param[in] listener The event listener
* @exception E_SUCCESS The method is successful.
* @exception E_OUT_OF_MEMORY The memory is insufficient.
- * @exception E_SYSTEM A system error has occurred.
