ChronoEnd (Function)

In french: ChronoFin

Stops a stopwatch and returns the time elapsed (in milliseconds) since the start of timing (call to ChronoStart). This stopwatch can be restarted by ChronoResume if necessary.

New in version 2025

Variables of type Chrono are now available in browser code. The syntax for handling Chrono variables also becomes available.

Example

// Démarrage du chronomètre 
ChronoStart()
MaFonction()
// Arrêt du chronomètre 
DuréeMaFonction is Duration = ChronoEnd()
Info("Le traitement MaFonction() a duré " + DuréeMaFonction)

// Démarrage du premier chronomètre 
ChronoStart(1)
// Démarrage du second chronomètre 
ChronoStart(2)
// Arrêt premier chronomètre
DuréeChronoDébut is Duration = ChronoEnd(1)
MaFonction()
// Arrêt du second chronomètre
DuréeMaFonction is Duration = ChronoEnd(2)
Info("Le traitement MaFontion() a duré " + DuréeMaFonction, ...
	"Le traitement complet a duré " + DuréeChronoDébut)

MonChrono1 is Chrono
MonChrono2 is Chrono
// Démarrage du premier chronomètre 
ChronoStart(MonChrono1)
// Démarrage du second chronomètre 
ChronoStart(MonChrono2)
// Arrêt premier chronomètre
DuréeChronoDébut is Duration = ChronoEnd(MonChrono1)
MaFonction()
// Arrêt du second chronomètre
DuréeMaFonction is Duration = ChronoEnd(MonChrono2)
Info("Le traitement MaFonction() a duré " + DuréeMaFonction, ...
	"Le traitement complet a duré " + DuréeChronoDébut)

Syntax

Ending the timing started with a stopwatch number Hide the details

<Result> = ChronoEnd([<Stopwatch number>])

<Result>: Duration

Time elapsed (in milliseconds) since the last call to ChronoStart for the specified stopwatch number.
This parameter is an integer.

<Stopwatch number>: Optional integer

Identifier of stopwatch used. If this parameter is not specified, its default value is set to 1.

This syntax is not available in PHP

Stopping the timing started with a Chrono variable Hide the details

<Result> = ChronoEnd(<Stopwatch>)

<Result>: Duration

Time elapsed (in milliseconds) since the last call to ChronoStart for the specified stopwatch.

<Stopwatch>: Chrono variable

Name of the Chrono variable that corresponds to the stopwatch to use.

Remarks

Miscellaneous

If ChronoEnd is called twice on the same stopwatch without ChronoStart being called, the returned duration will be identical for the two calls (the stopwatch is stopped during the first call to ChronoEnd).

Error

A WLanguage error occurs ("The stopwatch is not started") if ChronoStart was not called before ChronoEnd.

Threads and parallel tasks

Each thread (and each parallel task) includes its own stopwatches.

Two distinct threads (or two distinct parallel tasks) can perform separate timings by using the same stopwatch number.

The WLanguage error "The stopwatch is not started" will occur only if ChronoStart and ChronoEnd are not called in the same thread.
