Sounds like you really want to use a timer. Timers are easy to use, not "very hard".

See this code which executes a task after 5 seconds:
C#:

C#

namespace WindowsFormsApplication1
{
   public partial class Form1 : Form
   {
      public Form1()
      {
         InitializeComponent();
         Timer tmr = new Timer();
         tmr.Interval = 5000;
         tmr.Tick += new EventHandler(tmr_Tick);

         //Do some work

         tmr.Start();
      }

      void tmr_Tick(object sender, EventArgs e)
      {
         //Do some work after 5 seconds
         ((Timer)sender).Stop();
      }
   }
}

VB.NET:

Namespace WindowsFormsApplication1
	Public Partial Class Form1
		Inherits Form
		Public Sub New()
			InitializeComponent()
			Dim tmr As New Timer()
			tmr.Interval = 5000
			tmr.Tick += New EventHandler(AddressOf tmr_Tick)

			'Do some work

			tmr.Start()
		End Sub

		Private Sub tmr_Tick(sender As Object, e As EventArgs)
			'Do some work after 5 seconds
			DirectCast(sender, Timer).[Stop]()
		End Sub
	End Class
End Namespace

Does that look very hard to you? Just use 8 hours instead of 5 seconds and you are done like:

C#

tmr.Interval = 8*60*60*1000; //8 hours * 60 minutes * 60 seconds * 1000 milliseconds
