I need to map the answers to LimeSurvey questions to a timeline in order to synch these answers to other continuous measures.
To my knowledge, you can record the Start-Time of the survey and the time spent on every question group in seconds. If this is true, would it be possible to create a timeline of survey answers by just cumulatively adding the question-group timings to the start date?
Does somebody know if the Start-Date captures the actual time the partcipant opens the link to the survey (lands on the page) or the time he or she clicks "start survey"?
If somebody has an alternative idea how to reliably time-map LS-answers it would greatly be appreciated!
Just in case someone stumbles upon the same problem:
you can request epoch time markers and record them into a hidden text question. Fair enough if a resolution in seconds does it for you.

If anyone knows how to set time markers in milliseconds, please share!
