This functionality is available to new and existing customers at no additional cost. In the real word scenarios many application manipulate the date and time data types. Date types are highly formatted and very complicated. Redshift is an award-winning, production ready GPU renderer for fast 3D rendering and is the world's first fully GPU-accelerated biased renderer. CURRENT_TIME , CURRENT_TIMESTAMP , LOCALTIME , and LOCALTIMESTAMP can optionally be given a precision parameter, which causes the result to be rounded to that many fractional digits in the seconds field. If we consider my local timezone is Australia/Melbourne, Redshift offsets it by -10 hours across the column.
