How do I use the time zone calculator?

The time zone calculator allows you to convert time zones, showing you the time difference so you can plan a call or meeting with someone who is not in the same time zone as you.

Here's how to use it:

• Open the main app
• Tap on the time zone calculator icon at the bottom of your screen. 
• You will see a line of numbers appear. To convert the time, tap on the city that you would like to use as your starting point.
• Then, tap through to change the time for that city and the other cities in your list will convert automatically.

You can also share your list of converted time zones with others by tapping 'Share' and then 'More', or you can create a calendar entry which can also be shared with others by tapping 'Add to Calendar'.
