While registering I noticed a long list of Time Zone choices. Which do I use?

The time zones choices consist of a list large cities located within standard time zones. Pick a city that you share a time zone with. For example, New York uses the Eastern Time Zone, and if you are in New Jersey or Florida, you would choose New_York for your time zone. The list starts with eastern cites at the top and works westerly through the list.
