Hi Bdog,
Welcome to the Sony Community!
We appreciate the interest in the DSCHX80 camera and the PlayMemories Camera Apps that you can add to it. As of now, the time lapse app is not compatible with this model. But thanks for your feedback, we'll take note of this suggestion for future product and software developments.
You can check out the updates for the various PlayMemories Camera Apps here.
If my post answers your question, please mark it as "Accept as Solution". Thanks_Mitch
