How to use stopwatch in PowerShell?

PowerShellMicrosoft TechnologiesSoftware & Coding

To use the stopwatch in PowerShell, we need to use [System.Diagnostics.Stopwatch] class.

We will create a new object for this class,

$stopwatch = [System.Diagnostics.Stopwatch]::new()

Below are the members of the above stopwatch mentioned class.

PS C:\> $Stopwatch | gm


TypeName: System.Diagnostics.Stopwatch

Name MemberType Definition
---- ---------- ----------
Equals Method bool Equals(System.Object obj)
GetHashCode Method int GetHashCode()
GetType Method type GetType()
Reset Method void Reset()
Restart Method void Restart()
Start Method void Start()
Stop Method void Stop()
ToString Method string ToString()
Elapsed Property timespan Elapsed {get;}
ElapsedMilliseconds Property long ElapsedMilliseconds {get;}
ElapsedTicks Property long ElapsedTicks {get;}
IsRunning Property bool IsRunning {get;}

You can see above that you can Start, Stop, Restart, and Reset the stopwatch and before starting all values should be 0.

PS C:\> $Stopwatch.Elapsed

Days : 0
Hours : 0
Minutes : 0
Seconds : 0
Milliseconds : 0
Ticks : 0
TotalDays : 0
TotalHours : 0
TotalMinutes : 0
TotalSeconds : 0
TotalMilliseconds : 0

Now, we will start the timer using the Start() method.

$Stopwatch.Start()

You can check the elapsed time using the Elapsed property.

PS C:\> $Stopwatch.Elapsed

Days : 0
Hours : 0
Minutes : 1
Seconds : 42
Milliseconds : 284
Ticks : 1022842838
TotalDays : 0.00118384587731481

TotalMinutes : 1.70473806333333
TotalSeconds : 102.2842838
TotalMilliseconds : 102284.2838

To retrieve any of the above property, use the property name. For example,

Example

PS C:\> $Stopwatch.Elapsed.Minutes
