WPF/Winform Time Range Selector

I'm looking for a decent WPF or Winform time range selector, much like a home central heating system, where a time range is selectable.

Is there any GUI libraries or examples available to fulfill this need?

What you are looking for is called "radial" gauge controls.

If you search on google you will find lots of controls for Winforms and WPF.

Check out infragistics!! They have cool range sliders, I have been using infragistics over an year. Their custom support is fine, controls are very cool. Native WPF 4 controls.
