I'm having an issue when uploading a date from a csv via DataLoader. The date on my csv is for example 2017-04-03, but when uploading it via DataLoader, it will be 2017-04-02 in SF (always one day less).
The SF field is a Date field, not Date/time.
Any idea of what could be the problem? I'm trying to check the DataLoader settings but I'm on MacOS and nothing happens when I click "Preferences".
