inconsistent timing from .net StopWatch

c#,.net,timing,stopwatch,cudafy.net

As the TotalMilliseconds is constantly incrementing & you are trying to find differences between points in time, you need to subtract the sum of the preceding differences after the second one, hence : tIQR = watch.Elapsed.TotalMillisconds - (tHistogram + tHistogramSum); & tThresholdOnly= watch.Elapsed.TotalMillisconds - (tHistogram + tHistogramSum + tIQR); ...

How to measure invocation time of “Handle” method in NServiceBus?

c#,castle-windsor,nservicebus,stopwatch,nservicebus5

To measure all there is indeed performance counter but if that is not sufficient then you can create your own step in the NServiceBus pipeline. http://docs.particular.net/nservicebus/pipeline/customizing Create a custom behavior by inheriting IBehavior<IncomingContext> and implement the interface. You now have access to the IncomingContext argument which contain information about the...

Delphi Stopwatch time format

See http://docwiki.embarcadero.com/Libraries/en/System.SysUtils.Format labelSW.Text := Format('%2.2u:%2.2u:%2.2u:%3.3u',[Hour,Min,Sec,MSec]); The precision specifier makes left padding with zeroes. Using the RTL TStopwatch advanced record in System.Diagnostics, it gets a little easier: uses System.SysUtils, System.Diagnostics; var sw: TStopwatch; ... sw := TStopwatch.StartNew; // Start measuring time ... procedure TForm1.TimerSWTimer(Sender: TObject); begin LabelSW.Text := FormatDateTime('hh:nn:ss:zzz',sw.ElapsedMilliseconds/MSecsPerDay);...

How to use native Stopwatch with fewer decimal places?

vb.net,visual-studio-2010,timespan,stopwatch

I think your best options is just to use a Custom format for the Elapsed value (Which is a TimeSpan) like this: Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick Label1.Text = stopwatch1.Elapsed.ToString("dd\.hh\:mm\:ss\.fff") End Sub where fff is the optional number of milliseconds you require - just specify...

Stop watch java script without using Date.getTime()

javascript,stopwatch

As you've found out setInterval/setTimeout is not reliable. You must use a native time library to get a reliable time. Since you can't keep the time in JavaScript the idea is that you poll the time, and poll it often so that it looks close enough. If you naively do:...

Why property “ElapsedTicks” of List not equal to “ElapsedTicks” of Array?

c#,.net,stopwatch

Different code is expected to produce different timing. Second loop adds to array as question imply One most obvious difference is boxing in ArrayList - each int is stored as boxed value (created on heap instead of inline for List<int>). Second loop adds to list as sample shows growing list...

I want to be able to make something like a background stopwatch?

java,timer,stopwatch

You can do something like this: Calendar c = Calendar.getInstance(); int hrs = c.get(Calendar.HOUR); int mnts = c.get(Calendar.MINUTE); int secs = c.get(Calendar.SECOND); Then you can print the re-spawn time by printing System.out.printf("Monster will respawn in %d minutes and %d seconds", mnts+min, secs+sec); Of course you will also have to do...

Stopwatch Timer doesn't work properly

javascript,html,css,timer,stopwatch

You arent checking whether the timer is currently active when clicking start- and only running if not. As such, each time you click, the function is being run regardless...so you see it speeding up. To remedy, set time to null initiaally and when stopping, then check this state when starting...

StopWatch in seperate thread restart

c#,multithreading,timer,packet,stopwatch

There are several ways to implement this mechanism. Creating thread is the worst one. Be careful - accessing Stopwatch instance members from multiple threads is not safe. One easy and straightforward solution is to create ThreadPool Timer that ticks let's say every 15 seconds and checks boolean variable via Volatile.Read....

How to keep variables in dynamic array for a limited time

c#,arrays,loops,timer,stopwatch

What would probably work better is to create a Dictionary<string, DateTime> where you add the found key word and the time that it was found. Then create a method that is called via a timer with the body: foundKeywordsDict = foundKeywordsDict.Where(kvp => kvp.Value > DateTime.Now.AddMinutes(-5)) .ToDictionary(kvp => kvp.Key, kvp =...

Finding deltatime in C# using stopwatch
