trouble timing a method

[fguihen]

i have a method, and i take a time span at the beginning and the same at the end, and take them away, and i should be able to see how long a method takes to do its stuff, but in the miliseconds and ticks both come up as zero at the end. why is this? heres the code.

 

	public void DrawToScreen(Graphics h)
	{

		this.GetStartTime();
		this.processingStart = System.DateTime.Now;
		pen.Color = Color.Black;
		System.Drawing.Font f = new System.Drawing.Font("Arial",8);
		
		h.FillEllipse(new SolidBrush(Color.HotPink),(float)position.Xval,(float)position.Yval,diameter,diameter);
		Vector v = new Vector(this.position.Xval,this.position.Yval);
		v = this.position.Displace(60,8);
		h.DrawString(this.idNum.ToString(),f,new SolidBrush(Color.Black),(float)v.Xval,(float)v.Yval);
		if(this.ShowLines == true)
		{
			h.DrawLine(this.pen,(float)this.LeftSight.Xval,(float)this.LeftSight.Yval,(float)LeftSightEnd.Xval,(float)LeftSightEnd.Yval);
			h.DrawLine(this.pen,(float)this.RightSight.Xval,(float)this.RightSight.Yval,(float)RightSightEnd.Xval,(float)RightSightEnd.Yval);
			h.DrawLine(this.pen,(float)this.RightSight.Xval,(float)this.RightSight.Yval,(float)this.LeftSight.Xval,(float)this.LeftSight.Yval);
			h.DrawLine(this.pen,(float)this.center.Xval,(float)center.Yval,(float)FarSight.Xval,(float)FarSight.Yval);
			
			
	
			h.FillEllipse(new SolidBrush(Color.Red),(float)center.Xval,(float)center.Yval,4,4);
			
		}
		//just have thrown in variables to see contents of second, milisecond and tick 
		//parts of the timespan before and after 
		this.UpdatePos();
		this.processingFinish = System.DateTime.Now;
		int secs = Person.DiscountableTime.Seconds;
		float milli = Person.DiscountableTime.Milliseconds;
		long ticks = Person.DiscountableTime.Ticks;
		Person.DiscountableTime = DiscountableTime.Add((processingFinish.Subtract(processingStart)));
		int secs1 = Person.DiscountableTime.Seconds;
		float milli1 = Person.DiscountableTime.Milliseconds;
		long ticks1 = Person.DiscountableTime.Ticks;
	}

Where is Person.DiscountableTime declared and what do it's methods do?

As a simple test if you subtract processingStart from processingFinish does the resultant TimeSpan exhibit the same problem or does it reflect a change in time?

discountable time is a global time span variable that stores the total processing time of each bot and takes it away, so that bot 12 will not have the extra time spent processing bot1 -> bot 11 added to its time, making it inacurate
