Specify different date formats for multiple sources in ETL

I am combining a number of data sources with date columns using an ETL before performing other calculations on them.

 

Some of the sources have Australian date format (DD/MM/YYYY), and others have US format (MM/DD/YYYY).

 

The ETL gives me results in YYYY-MM-DD format, where it's actually incorrectly converted some of the dates to YYYY-DD-MM by assuming the wrong input date format. This means I end up with results from the future (eg 2018-12-03).

 

What's the best way to ensure the ETL always knows the correct input date format?

    Hi. @artywah

     

    Is it possible to avoid by replacing the date that is incorrectly converted by using regex?

     

    Set Column Type
      Column   : DateColumn
      Data Type: Text

    　Pattern A　YYYY-MM-DD (TEXT)

        Set Column Type
          Column   : DateColumn
          Data Type: Date
          Format   : Year first


    　Pattern B  YYYY-DD-MM (TEXT)

    　　Replace Text
    　　　Column            : DateColumn
          Search "Use Regex": ^([0-9]*)-([0-9]*)-([0-9]*)
          Replace           :  $1-$3-$2

        Set Column Type
          Column   : DateColumn
          Data Type: Date
          Format   : Year first

    Unfortnately this isn't working. It seems Domo is being too smart and processing the format before I can do anything with it in an ETL.

     

    It seems I need to set the date format as Domo imports the data (before I can perform an ETL on it)
