For a project I have been working on I needed a time picker control. Since such a control isn't part of the standard controls or part of the AjaxControlToolkit, I went to Google to search one out. The best free control I came across was from Excentrics World. I have found it to be highly customizable and it has fit my needs perfectly.
I decided to use time picker label with image from the many options.
When I initially added my clock image, it was pretty tight up against the five. Like I said above, you have a lot of styling choices, but unfortunately padding the label or image was not one of them that I found. I ended up using Paint.Net to add some white space to the left side of my image which did the trick.
