PowerShell: Using Timer to track time elapsed

New-TimerStopWatch.ps1

$timeout = New-TimeSpan -Seconds 30
$timer = [Diagnostics.Stopwatch]::new() # Create a timer
$timerAndStart = [Diagnostics.Stopwatch]::StartNew() # Create a timer and start it
$timer.Start() # Start the timer
$timer.Stop() # Stop the timer
$timer.Elapsed # Get time elapsed
$timer.IsRunning # Is timer running?
$timer.Restart() # restarts the time, doesn't stop
$timer.Reset() # stops timer and sets to 0
$timer.Equals($timeout) # check if timer value equals a value such as timeout, returns boolean

# How to utilize the timer
$timeout = New-TimeSpan -Seconds 30
$timer = [Diagnostics.Stopwatch]::StartNew() # Create a timer and start it
while ($timer.Elapsed.TotalSeconds -lt $timeout.TotalSeconds) {  
    # Show elapsed time in console
    Write-Output -Message "INFO: Waiting on timeout... Elapsed Time:" $timer.Elapsed.Seconds
    # If using Verbose output the "latest" time elapsed must be stored in a var as it cannot be added or used directly with Verbose messaging
    # To modify your PowerShell session to show Verbose set the environment variable: $VerbosePreference to: $VerbosePreference = "Continue" 
    $timeElapsedSeconds = $timer.Elapsed.TotalSeconds
    Write-Verbose -Message "INFO: Waiting on timeout... $timeElapsedSeconds"
    Start-Sleep -Milliseconds 500
} # While
Write-Verbose -Message "INFO: Timed out!"

Thank you for the example script.
Powershell is complaining about line 14
Write-Verbose : A positional parameter cannot be found that accepts argument '+'.
It seems the elapsed time for a each cycle of while is not being added to the total Elapsed time.
Thank you for helping me learn.

@RackoWacko, Thanks for trying out this Gist and finding the limitation of the Write-Verbose cmdlet. I've updated the Gist to provide a better example of using the Stopwatch diagnostic feature which I hope answers your questions and provides better guidance.
