I am having the same problem as well.
I’m using the following code in my theme functions file
function datepicker_to_unix( $date ){
$dateparts = explode('/', $date);
$unixtimestamp = strtotime(date('d.m.Y', strtotime($dateparts[1].'/'.$dateparts[2].'/'.$dateparts[0])));
return $unixtimestamp;
}
And then the following in my template file
<?php $date = get_field('field_name'); echo date('F d, Y', datepicker_to_unix($date )); ?>
The result outputs: January 01, 1970
