Your LimeSurvey version: 6.4.4
==================
Hello, I encountered a problem with the date of survey completion by the participant. Regardless of which survey I choose from the list of my active surveys, the responses downloaded from participants always have the value “1980-01-01 00:00:000” as the survey completion date. Whether I download the responses from the interface or via the API, whether the response was given today or a week ago - everywhere I receive the value “1980-01-01 00:00:000”. I will add that in the interface on the administrator panel, on the “Survey participants” list, I see that the “Completed?” date is displayed correctly.

Am doing something wrong? What needs to be done to get proper dates?
 

Surveys set to "anonymous" do show this "dummy" date to avoid merging by date and time
 

The way I want to conduct surveys requires that respondents are not anonymous.

Please, show it,
and ALL settings of your activated survey. (best some screenshots)

I found out that the setting responsible for this becomes available when one activates the survey: Date stamp.

It is also available in the ‘Notifications & data’ settings menu -> Date stamp -> On.

Mine was set to ‘Off’, that’s why it showed such a strange date.
