Learn How to design it

To create a new app in windows phone 8, the steps are listed below:
To create a new app in windows phone 8
  1. Create a new project by going through File | New Project | Windows Phone Application - Visual C#. Give a desired project name( World Clock is my app name).
  2. From Solution Explorer, open MainPage.xaml file. (If Solution Explorer  is currently not opened then open it via View>>Other Windows>> Solution Explorer).

  3. Change name of your header text, which is in TextBlock(Inside stack panel).
  4. Add a listbox control in the grid panel control. Also bind from ItemSource property.
  5. Add a class in the project, which name is "timezone.cs". Add two public property inside in it. Now, code look like
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    
    namespace WorldClock
    {
     class timezone
     {
     public String timename { get; set; }
     public string ImagePath { get; set; }
     }
    }
    
    
6.  Now add some utc time in the list collection with flag images. Also bind this with ListBox using DataContext
  List chemists = new List();
            chemists.Add(new timezone() { timename = "UTC-12:00 Internatioanl Date Line West", ImagePath = "image/Internatioanl Date Line West.jpg" });
            chemists.Add(new timezone() { timename = "UTC-11:00 Coordinated Universal Time-11", ImagePath = "image/Internatioanl Date Line West.jpg" });
            chemists.Add(new timezone() { timename = "UTC-10:00 Hawaii", ImagePath = "image/hawaii.jpg" });
            chemists.Add(new timezone() { timename = "UTC-09:00 Alaska", ImagePath = "image/Alaska.gif" });
            chemists.Add(new timezone() { timename = "UTC-08:00 Baja California", ImagePath = "image/bajaflag.jpg" });
            chemists.Add(new timezone() { timename = "UTC-08:00 Pacific Time(US & Canada)", ImagePath = "image/uscan.jpg" });

  7. Now, use DispatcherTimer class for update the time with 1 sec.  Now, use this code for update the time
DispatcherTimer newTimer = new DispatcherTimer();
newTimer.Interval = TimeSpan.FromSeconds(1);
            newTimer.Tick += OnTimerTick;
            newTimer.Start();
void OnTimerTick(Object sender, EventArgs args)
        {
           
         
            clocklabel.Text = DateTime.Now.ToString();
           
         
        }
8 .Create the code for each index of ListBox also display the result on MessageBox.

private void lstCountries_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            switch (list1.SelectedIndex)
            {
                case 0: MessageBox.Show(dt.AddMinutes(-720).ToString() + TimeZoneInfo.Utc.DaylightName);
                    break;
                case 1: MessageBox.Show(dt.AddMinutes(-660).ToString() + TimeZoneInfo.Utc.DaylightName);
                    break;
                case 2: MessageBox.Show(dt.AddMinutes(-600).ToString() + TimeZoneInfo.Utc.DaylightName);
                    break;
                case 3: MessageBox.Show(dt.AddMinutes(-540).ToString() + TimeZoneInfo.Utc.DaylightName);
                    break;
                case 4: MessageBox.Show(dt.AddMinutes(-480).ToString() + TimeZoneInfo.Utc.DaylightName);
                    break;
                case 5: MessageBox.Show(dt.AddMinutes(-480).ToString() + TimeZoneInfo.Utc.DaylightName);
                    break;

            }

        }
9. Run this app in Emulator WVGA 512mb, now code will generate the output.
