Quick example of how to use script blocks to track timing in an easy-to-wrap way in PowerShell for things like stages of a build

TimingExample.ps1

# Track build time components below
$steps = [System.Collections.Generic.List[PSObject]]@()

function TrackTime {
    Param(
        [string]$name,
        [scriptblock]$script
    )
    Write-Host ""
    Write-Host -ForegroundColor Blue "[$(([DateTime](Get-Date)).ToString("u"))] Step: $name"

    # Measure-Command doesn't stream output here so...can't use it. Do it the janky way.
    $step = @{ Name = $name; Start = (Get-Date); Success = $true }
    $steps.Add($step)
    Invoke-Command -ScriptBlock $script
    $step.Duration = New-TimeSpan -Start $step.Start -End (Get-Date)
}

function WriteFooter() {
    Write-Host -ForegroundColor Blue "[Build Summary]"
    Write-Host $("{0,-24} {1,-16}     {2,8}" -F "Step", "StartTime", "Duration")
    Write-Host "----------------------------------------------------------"

    foreach ($step in $steps) {
        if ($step.Success) {
            Write-Host $("{0,-24} {1,-16}    {2,8}s" -F $step.Name, $step.Start.ToString("hh:mm:ss.fff"), $step.Duration.TotalSeconds.ToString("0.00"))
        }
        else {
            Write-Host -ForegroundColor Red $("{0,-24} {1,-16}    {2,8}s" -F ($step.Name + " (Fail)"), $step.Start.ToString("hh:mm:ss.fff"), $step.Duration.TotalSeconds.ToString("0.00"))
        }
    }
    $totalDuration = (Get-Date) - ($steps[0].Start)
    Write-Host "----------------------------------------------------------"
    Write-Host -ForegroundColor Green "Overall build time: $($totalDuration.ToString("hh\:mm\:ss\.fff")) (hh:mm:ss) = $($totalDuration.TotalSeconds.ToString("0.000")) sec"
    Write-Host ""
}

# Your script!
TrackTime -Name "Init" -Script {
    Write-Host "Initializing"
    Start-Sleep -Seconds 2
}

TrackTime -Name "Short nap" -Script {
    Start-Sleep -Milliseconds 100
    # If you want to fail the current step: $steps[$steps.Count - 1].Success = $false
    # ...and it would render red with (Fail) beside, still rendering the timings to help the user.
}

TrackTime -Name "Zzzzzzz" -Script {
    Start-Sleep -Seconds 2
}

## Print timings out at the end somewhere...
