Some features in VMcast use your device's time zone settings. If you notice that the always on clock feature on your stream is showing the wrong time, you may need to update this setting. Here's how to change the time zone on your Amazon Fire TV stick.
Start from the Amazon Fire TV Home screen.
Press and hold the Home (⌂) button on the Fire TV stick remote for a few seconds. A quick access menu should appear covering the entire screen.
Press "Down" on the remote and select "Time Zone."
Select "Time Zone" again and select your preferred region.
Choose your correct time zone.
Relaunch the VMcast app and the clock should show the correct time.
