Is it possible to change the data retention settings of an already-created DE? I have DE's that are automated. An automation puts data view information into these DE's but when I edit, I cant see the option to modify the retention settings.
Also when it comes to time format for event dates in the data views (https://help.salesforce.com/articleView?id=mc_as_data_view_open.htm&type=5)
Is it for MC to store it as an EPOCH time instead of a specific time zone?"
