Hello All,
I am looking for an advice how to do calculation with the time. I do have a column with datatype 'timestamp with time zone'. The value is '2003-03-22 07:53:56-07' for instance. I would like to select it from the table with result of '07:59:59' – '07:53:56', so the query should return '00:06:03'.
Thank you for your time.
