Have a look at this simple DateTime example

[woodz]

Hello,

I could not follow the mechanism of the CLR how it updates the DateTime.Now property.
The following code should demonstrate my intention:

[STAThread]
static void Main(string[] args)
{
	for(int i=0;i<10;++i)
	{
		DateTime dt = DateTime.Now;
		Console.WriteLine("before the loop: ".PadRight(20,' ') + dt.Second + ":" + dt.Millisecond);
		for(int n=0; n<1000000; ++n);
		dt = DateTime.Now;
		Console.WriteLine("after the loop: ".PadRight(20,' ') + dt.Second + ":" + dt.Millisecond);
	}
}

The result of the output is:

before the loop:    33:905
after the loop:     33:921
before the loop:    33:921
after the loop:     33:921
before the loop:    33:921
after the loop:     33:921
before the loop:    33:921
after the loop:     33:937
before the loop:    33:937
after the loop:     33:937
before the loop:    33:937
after the loop:     33:937
before the loop:    33:937
after the loop:     33:952
before the loop:    33:952
after the loop:     33:952
before the loop:    33:952
after the loop:     33:952
before the loop:    33:952
after the loop:     33:952

My questions are:

Why dosen't the milliseconds change on every step?
Are there other approaches?

Thanks
