A bank has 4 clocks in its boardroom in London, set to the times at the major stock exchanges, namely, London, New York, Tokyo, and Hong Kong. Their offsets from UTC (Universal Standard Time) in winter are 0, 5, -9, and -8. Create six .cs programs. The first one is a base class LocalTime which contains a virtual DisplayTimeAndCity() method, the next four are four derived classes each of which displays local time in London, New York, Tokyo and Hong Kong, and the last one is a Test class which reads in a time in London, instantiates objects for each of the 4 Times, then prints them out with the city names.
