Date field issues

Hello,
can you solve this issue ?
Setting timezone indatabase.js make no difference…

atdbconnection: {

      connector: 'bookshelf',

      settings: {

        client: 'mysql',

        host: env('DATABASE_HOST', '127.0.0.1'),

        port: env.int('DATABASE_PORT', 3306),

        database: env('ATDATABASE_NAME', 'agrologic'),

        username: env('ATDATABASE_USERNAME', 'root'),

        password: env('ATDATABASE_PASSWORD', ''),

        ssl: env.bool('DATABASE_SSL', false),

        timezone: 'utc -3',

      },

      options: {

        autoMigration: false,

      }

    },
