How frequent is DateTime.Now updated? or is there a more precise API to get the current time?

Curiously, your code works perfectly fine on my quad core under Win7, generating values exactly 2 ms apart almost every time.

The problem with DateTime when dealing with milliseconds isn't due to the DateTime class at all, but rather, has to do with CPU ticks and thread slices. Essentially, when an operation is paused by the scheduler to allow other threads to execute, it must wait at a minimum of 1 time slice before resuming which is around 15ms on modern Windows OSes. Therefore, any attempt to pause for less than this 15ms precision will lead to unexpected results.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
