The time on my TV Guide is wrong. How can I fix this?

VMedia > TV > Roku
The VMedia TV application utilizes the time set on your Roku device to manage TV guide listings.  Please ensure the time is correct on your Roku device in order for the TV guide to display correctly.  To change the time on your Roku device, from your home screen please select Settings > System > Time and ensure the correct time zone and time are set.
