How accurate is the Stopwatch class?
Stopwatch class does accurately measure time elapsed, but the way that the ElapsedTicks method works has led some people to the conclusion that it is not accurate, when they really just have a logic error in their code.
Is Stopwatch thread safe C#?
Looking at the source code, it is thread-safe, but you must not use: Stop() , Reset() and Restart() . So, if you start a shared instance, does not modify it and call only ElapsedXXX properties, you should be fine.
Why is the time measured by a stopwatch precise but not accurate?
Precise measurements are not the same as accurate measurements. That means the stopwatch is extremely precise—it always gets the same measurement. However, the problem with your precise stopwatch is that it is not very accurate; you know that your dog runs a mile in exactly two minutes, not 2.999 minutes.
What is elapsed time in stopwatch?
By default, the elapsed time value of a Stopwatch instance equals the total of all measured time intervals. Each call to Start begins counting at the cumulative elapsed time; each call to Stop ends the current interval measurement and freezes the cumulative elapsed time value.
