This is by design and it's to save battery life. If the phone cannot sleep then the battery will discharge very quickly and your app will be a battery drain. I was coding a timer myself and Mark recommended that I use notification manager for long-term timing instead and it was good advice.
I suggest you re-think your approach. Here's a brief summary of the approach I took: When an android device sleeps onPause is called in your activity. Override onPause and create notifications for the events you are timing, and save the timer info into shared preferences. When your device wakes onResume is called, in Override onResume and set up the countDownTimer calculating time left using the values from shared preferences. This approach means you have more work to do, you must learn notifications, you must create intents that deal with the notifications, etc. However it will make as better end product.
