I would like to know how long a command that I entered into my terminal has been running. It would be great to be able to get the timestamp of every command in my history. Let me know if you need any more information in order to be able to answer this question. Thanks.
EDIT: I am using a bash terminal.
Assuming you are using command prompt
then
