Timestamps of 1/1/1970

Hi,

Upon reviewing some data from our recent field effort we found that a handful of cases recorded the date 1/1/1970 from a current time question. In the paradata these cases also carry the 1/1/1970 date for interview_actions, etc. It seems to be across a few different interviewers. Do you know was it caused by tablet times set incorrectly? or some kind of glitch on the server end?

Thanks!

The easiest is to inspect the user profile and check what was the tablet time during the last synchronization.

Or simply call the interviewers and ask if the tablet settings are ok and were/weren’t changed during the survey.
