How Could I change date Format UTC to EST in Grails API Response?

Currently, I am migrating my server and database from UTC to EST. All, the data and server timezone in EST. But I am still getting the date in UTC for grails API. How could I resolve it?

Start by reviewing how Grails serializes dates in API responses and how timezone settings are applied across the server and database. Reproduce the UTC response with the reported migration setup, then verify that the response uses the intended timezone without breaking existing date handling.
