<# .SYNOPSIS Handle time measurement .DESCRIPTION Handle time measurement from when a cmdlet / function starts and ends Will write the output to the verbose stream (Write-PSFMessage -Level Verbose) .PARAMETER Start Switch to instruct the cmdlet that a start time registration needs to take place .PARAMETER End Switch to instruct the cmdlet that a time registration has come to its end and it needs to do the calculation .EXAMPLE PS C:\> Invoke-TimeSignal -Start This will start the time measurement for any given cmdlet / function .EXAMPLE PS C:\> Invoke-TimeSignal -End This will end the time measurement for any given cmdlet / function. The output will go into the verbose stream. .NOTES Author: Mötz Jensen (@Splaxi) #> function Invoke-TimeSignal { [CmdletBinding(DefaultParameterSetName = 'Start')] param ( [Parameter(Mandatory = $true, ParameterSetName = 'Start', Position = 1 )] [switch] $Start, [Parameter(Mandatory = $True, ParameterSetName = 'End', Position = 2 )] [switch] $End ) $Time = (Get-Date) $Command = (Get-PSCallStack)[1].Command if ($Start) { if ($Script:TimeSignals.ContainsKey($Command)) { Write-PSFMessage -Level Debug -Message "The command '$Command' was already taking part in time measurement.
