Q: How do I change my time zone?
There are two time zone settings you can set.
Store time zone
This is them time zone of where store/location is located. You can change the store time zone by going to 
> Store Settings > General Settings.
My time zone
This is time zone you are currently located. In most cases, this would be the same as the store time zone, but you may have stores/locations that are in other states in a different time zone. You can change your time zone by going to > My Settings > Local Settings.
