Create an all-day event using Native API

In order for an event to be treated as an all-day event by Sitefinity CMS, it must comply with the following:

The start time must be set to 12:00:00 am.
The end time must be set to 12:00:00 am.
The start and end date should be created in UTC format.
The event’s AllDayEvent property must be set to true

The following code creates an all-day event that lasts only one day with specified ID, Title, Content, StartDate, EndDate through the Native API:

using System;
using Telerik.Sitefinity.Modules.Events;
using Telerik.Sitefinity.Events.Model;

namespace SitefinityWebApp
{
   public partial class EventSnippets
   {
       public void CreateAllDayEvent()
       {
           EventsManager manager = EventsManager.GetManager();
           var eventTitle = "Title normal all day event-1";
           var eventContent = "Content normal allDay event-";

           DateTime eventStart = new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 0, 0, 0, DateTimeKind.Utc);
           DateTime eventEnd = eventStart.AddDays(1);

           string timezoneId = TimeZoneInfo.Utc.Id;
           Guid eventGuid = Guid.NewGuid();

           Event allDayEvent = manager.CreateEvent(eventGuid);

           allDayEvent.Title = eventTitle;
           allDayEvent.Content = eventContent;
           allDayEvent.EventStart = eventStart;
           allDayEvent.EventEnd = eventEnd;
           allDayEvent.AllDayEvent = true;
           allDayEvent.TimeZoneId = timezoneId;
           allDayEvent.ApprovalWorkflowState = "Published";

           manager.Lifecycle.Publish(allDayEvent);
           manager.SaveChanges();
       }
   }
}
