You can change how JSON serialization handles times zones in your Startup class by configuring AddJsonOptions in ConfigureServices method.

public void ConfigureServices(IServiceCollection services)
{
 services.AddMvc().AddJsonOptions(options =>
 {
 options.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;
 });
}
