I'm trying to create function in redshift that will calculate the exactly gap between two dates, like timestampdiff in MySQL. To calculate the difference between two timestamps, you can use the DATEDIFF () command: DATEDIFF () accepts the same values as EXTRACT () and DATE_PART (). Data warehouses like Redshift and Snowflake have a super useful DATEDIFF function – given two timestamps and a date part (hour, year, week, etc) it'll return how far apart they are. Amazon Redshift doesn't validate POSIX-style time zone specifications, so it is possible to set the time zone to an invalid value. Note: As TT rightfully wrote in his comment,.
