                change({ userAction, value }) {
                    if (userAction) {
                        scheduler.scrollToDate(DateHelper.set(value, 'hour', 21), { block : 'end', animate : 500 });
                    }
                }
            },
            highlightExternalChange : false
        }]

});

if you remove the workingTime : { fromHour : 15, toHour : 22 }, the scrollToDate function runs smoothly, but when added, the scroll seems to not work properly, as you can see in one of the videos
