 FACT: At the dinner table, Julie is told that it is earlier in  Columbus, where Harriet is calling from, than where she lives in New  York. In fact both cities are in the same Eastern Standard Time  Zone. In the book, Harriet is calling from Milwaukee in the Central  Time Zone, which is correct. However, when the screenplay changed  her location to Columbus, the writer failed to realize this fact and  change the dialog or the city.
