East or West coast TV programming Service

It will effect your regional and local channels.
But, outside of your local area, you won't get local channels anyway.
The regional sports channels such as MASN (regional sports) will change according to the address you use for service. Because we like to watch Orioles and Nationals baseball games, we kept our address in DC. During the winter, we can change our address to where we happen to be.
As for time, cable channels often broadcast shows twice, about three hours apart. IOW, if you watch something on the east coast on Discovery channel from 8-9PM, it is often shown again at 11PM east coast time, which is 8PM California time. Yes, the time in which you watch the show will change depending on your time zone.

If they are in fact allowing a choice, they are in violation of FCC rules & rags.

Your "billing" address dictates your E/W feeds. There is NO choice anymore. That is why we no longer have E/W feeds and just change our "service" address when we travel, so we get the locals in the area and not have to pay any extra for something that is free.
