Try calling XHome Services 1-877-298-0874
Hello marcbrad, there should be a clock icon on your XHome touch screen that will allow you to reset the date and time. You can click on this link for more information on how to access all of your apps and features.
The clock itself cannot be customized - the time is automatically configured based on the location and time zone of your account.
Have you tried restarting your Xfinty Wireless Gateway and Touchscreen yet? This might synch things back up.
The easiest way to do this is with our Xfinity My Account mobile app.
Once you've logged in to that app, click on the Internet icon and choose "Troubleshooting." Follow the prompts and wait for the reset process to complete (about 5 to 10 minutes).
Next, do the same for Xfinity Home. In the My Account app, click on the "Home" icon, tap the picture of your Touchscreen, select "Troubleshoot" and then "Restart Touchscreen." This process will take about 5 minutes.
Once the Touchscreen is back up, check the clock to see if you're all fixed up.
If that doesn't correct the issue, please give us a call at the number RobertWy posted above; it's possible there is a setting on your account that is incorrect which is causing the wrong time to be sent to the Touchscreen.
I hope that helps!
Comcast reply is not at all useful. They have told us how to change the display appearance, not the time.
I would call them and schedule a tech visit as a last resort.
