I'm using the package Nuget SwashBuckle AspNetCore with the web interface for my .Net/C# API. Thanks ! EDIT : it look like it's not due to swagger but JSON formatter. I close it. Swagger auto convert date time in UTC Hello, I've got a problem using Swagger for my API. In a in-parameter (of a GET method), I've got a datetime that people can give to the API, for example '2019-03-22T23:00:00Z'. But when I look at what swagger API receive in the parameter, I've got '2019-03-23 01:00:00'. It look like swagger want to convert it in UTC datetime, but what I want it's just to keep the same datetime value, without using the time zone. The date have one day difference and that's very annoying for me... How can I do ? Thanks ! Audric Solved
