If you'd like to monitor how long a script takes to run, you could use Measure-Command, but this cmdlet is for diagnostic purposes only and omits any script output.
Another approach just takes two snapshots and at the end, calculates the time difference.
This would tell you how long the cmdlet Get-Hotfix takes, including the time it takes for the cmdlet to output the data:- $start = Get-Date
- Get-HotFix
- $end = Get-Date
- Write-Host -ForegroundColor Red ('Total Runtime: ' + ($end - $start).TotalSeconds)
