Java(Spring) automatically correcting date by timezone bug

so I have a task to fix a bug. So basically I make a GET request for /report-information and get in response two fields: Date dateFrom, Date dateTill.

The correct date that it should return should be: 2019-07-01 00:00:00 and 2019-07-31 23:59:59 - that's the data from a database. Basically, I make a GET request for these fields, Java takes it from database and sends it back to me.

But the problem is that somehow the values that are returned after making a GET request are: 2019-06-30 21:00:00 and 2019-07-31 20:59:59. Basically -3 hours because of some automatic timezone correction.

What I need is to create a method or something similar that would make java ignore the timezone and wouldn't change the date. I should use Date variables not to mess up a lot of other code that uses these fields.

Also I should mention that when I debugged the whole process, somehow in the @RequestMapping method it returns these fields correctly, as they should be, but when I make a request through my browser or Postman, I get the corrected by timezone version of the date. But it is possible that I just missed something.

Do you have any suggestions or ideas why and at what moment does Java change the date automatically? And what should I do to prevent it from correcting the date.

Thank you!

Since you have mentioned that in your Controller code you can see the correct date, you may want to check the Jackson serializer ( assuming this is the one serializing objects to json ) settings used for serializing the date object into JSON. You can check the multiple options for configuration here.
