Google Spreadsheet: Dates are shown as "1-1-1970 0:00:00" in the spreadsheet

The problem occurs each time a new entry is done. All the date fields of the new entry are shown like "1-1-1970 0:00:00". If I then break the integration and create it again all entries are shown correctly (so also the last entry). However once a new entry is done the dates for this entry will be shown incorrectly. So rebuilding the integration has the effect that all the former entries are being shown correctly but it doesn't solve the problem that each new entry (after the rebuilding of the integration) will be shown incorrectly.

Kind regards,

Can you please confirm if you are using a locale setting on the sheet? Or using another app with it? If so, please try to create a cloned version of your form and create the integration without setting a locale and let us know if the issue still persists.

Also, please let us know which form is presenting this problem so we can make further tests in case the above didn't make any difference.
