how do i calculate relative time in Listbox elements

Question

I am binding a Listbox with a List which contains Minutes(200), how do I display relative time, like:

• 2 hours ago
• 3 days ago

• 1 month ago

  <ListBox x:Name="listBox">
   <ListBox.ItemTemplate>
     <DataTemplate >
  
       <TextBlock x:Name="TxtDuration" Text="{Binding Duration}"/>
  
    </DataTemplate>
  </ListBox.ItemTemplate>

You need something called a relative time converter.

If you search online, you'll find plenty of different implementations. A good one is definitely a part of Callisto toolkit.

You can also check out similar questions on StackOverflow such as this one.

Using a converter is really straightforward.

<TextBlock x:Name="TxtDuration" Text="{Binding Duration, Converter={StaticResource RelativeTimeConverter}}"/>

In this case the RelativeTimeConverter is declared as a static resource somewhere in your app.
