Log timestamp in Unix time

If this template helps then use it. If not then just delete and start from scratch.

OS : Windows 10
PsychoPy version : 2021.2.3
Standard Standalone? Yes
What are you trying to achieve?:
I would like to log the time of onset and offset of my stimuli and the subjects response in Unix time instead than time elapsed. I have to match my stimuli with data coming from a VR headset (off-line) for whom I have timestamp in Unix time.
Actually, I do not care much about extreme precision of timing, since I have just to roughly get a time window (in the order of the tens of seconds).

What did you try to make it work?:
I guess not much, I have tried to have a look to actually code the whole experiment, but I have to confess that what was appealing in psychopy was that such a simple experiment like mine would be extremely easy to setup (I literally just need to show some instructions and then 5 images for 10 seconds each and register one keypress). If I have to code from scratch it becomes suddenly less appealing.

This might help

@wakecarter, thanks for your answer. Indeed it is the type of solution that I have adopted. I just thought that there was a way of doing it automatically from the builder that I was missing somehow.

Lots of things in Builder require the addition of code components. Use Builder to create the structure of your experiments and the code components to go beyond the capabilities of the standard components.
