Syntax

Indicating the value of a timing started with a stopwatch number Hide the details

<Result> = ChronoValue([<Stopwatch number>])
<Result>: Duration
Time elapsed (in milliseconds) since the last call to ChronoStart for the specified stopwatch number.
PHP 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.

Indicating the value of a timing started with a Chrono variable Hide the details

<Result> = ChronoValue(<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

After calling ChronoEnd, all the calls to ChronoValue will return the value of the stopwatch when ChronoEnd was called.

Error

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

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 ChronoValue are not called in the same thread.
