Open Source means free as "free speech" but not as in "free beer". At first glance, it may not look like it, but even this "tiny" clock app takes a lot of time to maintain because of the quirks of different Android versions and devices in combination with auto text sizing and the DreamService implementation (FireTV!!!).

Screensaver on Amazon FireOS / FireTV

Amazon FireOS (on FireTV devices) does currently not officially allow changing the system screensaver to another (3rd-party) app. While nobody understands this decision Amazon made, there is a workaround possible using the Android developer tools. Without this workaround, the clock can still be started on FireTV devices like a normal app.

1. Enable Debugging on your FireTV.
   All details (including how to install ADB on your computer) are described here.

2. Execute the following command

   # execute this command to set this app as screensaver
   # please note: after that, the FireTV settings app still shows the Amazon screensaver, but the underlying Android system will now start the clock instead
   adb shell settings put secure screensaver_components systems.sieber.fsclock/systems.sieber.fsclock.FullscreenDream
   
   # if you want to restore the Amazon default screen saver, execute the following command
   adb shell settings put secure screensaver_components com.amazon.ftv.screensaver/.app.services.ScreensaverService
