Displayed time in feedback

Hey, I need some help with feedback and I would be really grateful if you could help.
I would like to include in the feedback the time during which the respondents responded to a given picture and I want it to be displayed so that they can see it.

Thank you for all the answers.

You can access the time since the routine began using the variable “t” - so if you set a Textbox component’s contents to Update each frame and set the value to $t it will display a time counter
