appointments show wrong time in different time zones due to daylight time changes.

The issue can be reproduced in scenarios:

- For US time zone 14th of march: If I click an empty slot, I have a popup that tells the time that is clicked. I click on the 9 AM slot and it says I'm clicking on "10:00". This only happens on 3/14/2021

- For European countries time zone: on 28th or march 2021 when is the daylight saving time

Image gets a really dark or light when saving in a jpeg format. It works for png.

When you zoom in on the graph, it always zooms to the center of the dataset. Even if I try to move, manually, horizontally the graph I lose the position when a point is added.

When point is added and chart is zoomed, cannot scroll to see other data, the chart reset the data visualization from the beginning.

Giving a RadDataGrid where columns are mostly empty, scroll to the right and mutate the data. All the rows without data visible disappear until the user scrolls back to columns that have data.

Sample project attached.

When having many stack bar series in one chart, some data points are rendered behind another data points. Check the attached image: how it looks on android and on iOS

When the culture is set on app level and using resx files, localization does not apply. 

When changing the device culture, the resx files apply the values.

While in DayView (or any other appropriate view), allow for appointments to be draggable to another time slot for rescheduling. 

Exception occurs when there are no items in the collection and load on demand mode is automatic: 

public ViewModel()
{
    this.Source = new ObservableCollection<string>();
    //for (int i = 0; i < 14; i++)
    //{
    //    this.Source.Add(string.Format("Item {0}", i));
    //}
    this.LoadItemsCommand = new Command(this.LoadItemsCommandExecute);
}
