Swapping your Home City and World Time City

You can use the procedure below to swap your Home City and World Time City. This 
capability can come in handy when you frequently travel between two locations in 
different time zones.

Home City and World Time City are swapped while the 
Home City originally is 

TYO

 (Tokyo) and the World Time 

City is 

NYC

 (New York).
