DataSets by default will use mysql date format, as that’s what mysql date/time functions return, so if you’re using filters for example the comparison needs to make sense.
That being said, you can format the output, perhaps by using formula type column, like in this example - DATE_FORMAT in Ticker?
So the end user will see the date in a more user friendly format, please see here for more parameters values you can use https://www.w3schools.com/sql/func_mysql_date_format.asp
