[Plugin: Advanced Custom Fields] Allow for filtering of various values

For example, :
./core/fields/acf_field.php acf_Field::get_value()
$value = apply_filters(‘acf_get_value’, $value, $post_id, $field);

./core/fields/acf_field.php acf_Field::update_value()
$value = apply_filters(‘acf_update_value’, $value, $post_id, $field);

My use case, I’m using the datepicker input type, but want to save the values in PHP-style timestamps (whole seconds) not js-style timestamps (with milliseconds), and want to build some filters to intercept and convert those values.

Thanks
