The TimePicker control uses TimeSpan values for all time properties like Time, DefaultHighlightedTime, MinimumTime, MaximumTime, etc.

With .NET 6 a new TimeOnly type was introduced. It would be great if the Time(Only)Picker would support it as well.

For now, I created a custom TimeOnlyToTimeSpan Converter and use it to bind the TimeOnly properties from the ViewModel. But native support would be great.

I have the following setup:

<telerik:RadTimePicker x:Name="picker" MinuteStep="5" SpinnerFormat="HH:mm"/>

When opening first time the picker already shows time for example 11 : 00

So I did not change the values of hours and minute and clicked OK . The Time property reflects data as 11 : 21 (current time on device ) instead on 11 : 00 which is confirmed by clicking OK.
