All over sudden the datepicker field returns a wrong date, every datepicker field is one day too early. Even if I save the post, the saved data ist still one day early. It worked as expected before, just stumbled over that during a birthday cronjob. Am I overlooking something? Help is gladly appreciated.
F.Y.I: Checking the post vars shows the right value to save:
acf[field_55b9e5d6b6561] = 19691123, that means 23. November 1969. So it is stored right into the database.
I tried two things:
$timestamp = strotime('19691123');
$birthdate = date_i18n( get_option( 'date_format' ), $timestamp );
which brings the wrong day: 22. November 1969
$timezone = new DateTimeZone(get_option('timezone_string'));
setlocale(LC_TIME, "de_DE.utf8");
$geburtsdatum = '19691123;
$geburtsdatum_dt = new DateTime($geburtsdatum , $timezone);
$birthdate = $geburtsdatum_dt->format(get_option( 'date_format' ));
which brings the correct date, but unfortunately in english language.
I of course can replace the month names in the strings, but that does not solve the root of the problem: The field in the backend is still showing the wrong date. Any thoughts on this? I am a bit in despair …
