Change Date type from MM/dd/yy hh:mm to yyyy-MM-dd

Dates and times can be challenging in Dataiku. One of the key aspects of using dates and times in dataiku is that you have to parse them into a format that dataiku understands as a date time value. Generally recorded in GMT time. You specified the specified a very particular output format yyyy-mm-did. If you need exactly that for some process further down your flow or beyond. You will likely have to use the formula editor to extract the date parts and concatenation your final result. Be careful with this process. Time zones can cause you challenges.

I would tend to carefully parse the date time and output the results parsed in the standard way to the next steps in the process. And not try to reformat in a yyyy-mm-dd format for output. (That just me, and your situation may mandate a different approach. )
