I have integrated google calendar v3 api in my mvc application and i am adding event by custom date and time.My application is hosted on Indian server and the the timezone for calendar is central time zone since the user lives in USA.SO whatever date i put in form and submit in calendar it always changes it to usa timing.
Please help me

What I have tried:

var folder = System.Web.HttpContext.Current.Server.MapPath("/App_Data/MyGoogleStorage");
           var credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                           new ClientSecrets
                           {

                               ClientId = "xxxxxxxxx-xxxxxxx.apps.googleusercontent.com",
                               ClientSecret = "xxxxxxx",
                           },

                           new[] { CalendarService.Scope.Calendar },
                           "user",

                           CancellationToken.None,
                           new FileDataStore(folder)).Result;

           // Create the service.
           DateTime eventdate = Convert.ToDateTime(bdate);
           int evyear = eventdate.Year;
           int evmonth = eventdate.Month;
           int evday = eventdate.Day;

           DateTime eventtime = Convert.ToDateTime(btime);
           int evhour = eventtime.Hour;
           int evendhour = eventtime.Hour;
           int evmin = eventtime.Minute;
           int evendmin = evmin + 60;

           if (evendmin > 60)
           {
               evendmin = evendmin - 60;
               evendhour = evendhour + 1;
           }
           else if (evendmin == 60)
           {
               evendmin = 00;
               evendhour = evendhour + 1;
           }
           var service = new CalendarService(new BaseClientService.Initializer
           {
               HttpClientInitializer = credential,
               ApplicationName = "ANNA'S RESTAURANT",
           });

           var myEvent = new Event
           {
               Summary = "Name :" + Name + System.Environment.NewLine + "Person : " + pno,
               Description = "Phone No :" + phoneno + System.Environment.NewLine + "Special Request : " + srequest,
               Location = "607 Happy Valley Rd Glasgow , KY",

               Start = new EventDateTime
               {
                   DateTime = new DateTime(evyear, evmonth, evday, evhour, evmin, 0, 0),
                   TimeZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time").ToString()

               },
               End = new EventDateTime
               {
                   DateTime = new DateTime(evyear, evmonth, evday, evendhour, evendmin, 0, 0),
                   TimeZone = TimeZoneInfo.FindSystemTimeZoneById("Central Standard Time").ToString()

               },

           };

           var recurringEvent = service.Events.Insert(myEvent, "primary");
           recurringEvent.SendNotifications = true;
           recurringEvent.Execute();
