Simplify analysis, increase performance, and ensure consistency Redshift provides many date and string functions that you can use to play around date type. ConvertTimeFromUtc(utcDateTime, timeZone); This takes into account things like day-light savings which can trip you up if start saving localized dates. In theory, one could have a measure column for each timezone, or a date column for each timezone and still only have one record per day, taking advantage of the columnar storage of Redshift and reducing Redshift date functions with syntax, definition and examples on the most frequently used 15 by developers. In this article, you will learn about different Amazon Redshift Timestamps data types I know that I can the session timezone with SET TIMEZONE TO 'CET'; But is there a way to get it back? I want something like SELECT SESSIONTIMEZONE, SYSDATE, SYSDATE::timestamptz, In Redshift, you cannot use the cluster parameter group to set the TimeZone configuration parameters. W By using the CONVERT_TIMEZONE function in Amazon Redshift, you can easily convert UTC timestamps into your local time zone for reporting, analytics, and Tested using Redshift 1.
