Your sample code doesn't quite do what I want. I want the user to only see the "1pm" version in the dialog window. But I want to save the 24-hour integer for use by the code. So I don't want to update #field_time.value with the converted-to-integer value; I want it to stay as the user entered it. <p>Your sample code doesn't quite do what I want.</p> <p>I want the user to only see the "1pm" version in the dialog window.
