If I understand your example correctly, it is about using time zones as a proxy for "regions where a TV show might be broadcast", which is clearly inadequate but because time zones are coarse and unrelated to the actual data of interest, not because broadcasting times are represented with timezones. (There might or might not be a second layer of error: 13:00 central time is the same time as 14:00 eastern time, 1 time zone to the east, and pretending they are different is a horrible abuse)
