Insert time stamp into the list, when feature is activated

Hello All,
Today I am going to show how to insert time stamp into list when feature is activated or deactivated.
Steps:
1. Add a sharepoint empty project and add a webpart to it.
In the web part insert the following code.

1 2 3 4 5 6 7 8 9 10 11

[ToolboxItemAttribute(false)]   public class MyWebPart : WebPart { protected override void CreateChildControls() { Label lbl = new Label(); lbl.Text = "Feature Activated"; Controls.Add(lbl); } }

2. Now right click on the feature and select the “Add Event Receiver“
Uncomment the FeatureActivated block and insert the following code.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

public override void FeatureActivated(SPFeatureReceiverProperties properties)  {  SPSite site = properties.Feature.Parent as SPSite;  SPWeb web = site.RootWeb;   SPList list = web.Lists["Features Tracker"];  if (list == null)  {  Guid listid = web.Lists.Add("Features Tracker", "Trakcs the feature activation time", SPListTemplateType.GenericList);  web.Lists[listid].Fields.Add("Activated Time", SPFieldType.DateTime, true);  SPView myview = web.Lists[listid].DefaultView;  myview.ViewFields.Add("Activated Time");  myview.Update();  list.Update();  }  SPListItem listitem = list.Items.Add();  listitem["Activated Time"] = DateTime.Now;  listitem.Update();  list.Update();  }

you can see the time stamps as below after deployment.
