Synchronizing Chat Times Across Different Time Zones
Mark from Sydney, Australia, and Hans from Berlin, Germany, want to coordinate their chat times. By using world time charts, they can determine the suitable time to log in simultaneously. In this scenario, we aim to find out what time it is in Berlin when it's 7:00 PM in Sydney. By applying mathematical techniques such as time zone conversions, we can solve this challenge efficiently.

Mark (from Sydney, Australia) and Hans (from Berlin, Germany) often communicate with each other using chat on the Internet. They have to log on to the Internet at the same time to be able to chat.
