Title: Convert timezone function

Hi, there is simple function to convert date from one timezone to another. Can be used like this
````
SELECT CONVERT_TZ(date, 'UTC', 'America/Adak') AS shifted_date FROM table
````
This query returns shifted date by difference between these timezones.

Thanks for review
