Why Time Difference Differs For The Same Application !?

[HTB]

Hi,

I have an application, I made a time difference (in millisecons)
between two auto events within the application.

I ran it twice, but the result (milliseconds) is not the same.

WHY !?

Curse you relativity! Was the first one slower?

You might want to read up on Chaos Theory.

That and if you measure finely enough, you will note its never an identical span of time.

At first it was samller, then it increased, after that it came back
to the first value !


OK, I read that, very interesting. But I have to ask why the
milliseconds in DateTime have 7 digits, while I know
they are 4 digits (1 second = 1000 milliseconds) !?

You might want to know how many milliseconds total there are. If you want just the recent number, mod it by 1000.

You are doing something like:

DateTime start= DateTime.Now;
//do all that code stuff you want to measure
TimeSpan t=(DateTime.Now-start);

Right?
I mean if you are doing any sort of I/O in your routine then it will never run the same time twice (well, depends on your precision)
