Even if this is an awesome component, I'm noticed that sliders was not so comfortable for changing time. So I felt free to add some modifications on your work. I simply replaced the button to open your time picker popup with a spinner, in order to choose time without open another popup.
i have just one question about your spinner datetimepicker,, can we use use your componment with internet explorer. Because when i used firefox or chrome there is no problem, but when i switched to explorer it doesn't work.
honestly I can't remember very well about the component, I worked on it about 2 years ago.
But I can tell you that a requirement of the project using the component was to run on IE (I can't rememeber which version, maybe IE8), perhaps the component was no longer compatible with later versions of IE.
Anyhow you can try playing around IE compatibility modes (x-ua-compatible meta tag or doctype)
