Okay nevermind, I figured it out but thank you anyway for offering help. The solution in this thread
works. I confused the .log with the .csv files. The .csv files display the time stamps set with
thisExp.addData(“routineStart”, time.time())
in the custom code component.
If someone with a similar issue reads this later, please be aware that this approach does not apply the system clock to every component and their events in the .csv file such as “example_text123.started”. The components still use a counter beginning with the experiments start. I guess you would have to find the place in your experiments code, where the main timer starts/is set to 0 and then set it to your system time.
The simpler solution was sufficient for our study, yet I guess there are different instances where you would want such a feature (having a gui implementation of a custom start time setting would also be a nice addition).
