Inserting "Second" along with Hour:Minute

I need to insert “Second” in my Time Format (along with Hour:Minute). Is it possible?

Welcome to the community, @urstpkobo050611! This post discussed previously should help you solve your issue:

It doesn’t work! If I use

regex( . , ‘^(\d*:?\d+:\d\d)$’ )

function, will the time be inserted as “hh:mm:sss”?
I tried but it doesn’t work.
Can you share any link of a video showing this?
I am extremely sorry to disturb you once again.

@urstpkobo050611, do you want to capture it manually or would you wish the system to capture it for you?

I want to capture it automatically (system) to capture. Have there any way, brother?
