Yes. From the bottom of TFA:

Scheduled Tasks

AWS Lambda functions can be triggered by external event timers, so functions can be run during regularly scheduled maintenance times or non-peak hours. For example, you can trigger an AWS Lambda function to perform nightly archive cleanups during non-busy hours.

Reliability is my real question around not only this, but lambda as a whole. I'll need to dig into the docs on that.
