I have followed the directions for setting the time zone region on my Deco XE5300 mesh network and when I select Chicago as the Region it is off by exactly 12 hours. If I change it to New_York, the time is correct (+1 hour from Chicago). If I change it to Denver, the time is correct (-1 hour from Chicago). 

Does anyone know why Chicago is not correct and how to get it set properly? 

As an example, it was 12:17 PM in Chicago when I selected that as the Region but the time for the devices was set to 12:17 AM and not PM. When I selected New_York the time was properly set to 1:17 PM.

I tried another Region option (North Dakota/Beulah) after Googling and finding that they are in the Central U.S. time zone as well...but the same problem exists for that Region option as well.

This makes using the child features of the Deco devices to be challenging as I now have to remember to set the times I want to use to the other region times...or set them to be off by 12 hours.

Thanks for any help or suggestions!
