How to find out how long a process has been running for?

Question

Is it possible to use wmic or powershell to find out how long a process has been running for?

If not, is there any other mean to obtain this information from Windows OS?

Answer 1

Use New-TimeSpan –Start; passing the StartTime property of the process which you want to know how long has been running. Here an example which shows how long notepad has been running:

PS C:\> New-TimeSpan -Start (get-process notepad).StartTime
