I need to be able to make it so the highlighted option on the timepicker, when open the drop down is the default time.
Then users will be able to scroll up for an earlier time and down for a later time.
this sounds like you need dynamic set to true.
To build on this:
the timepicker needs to be able to have to scroll position to a default value without necessarily setting the value of the text box.
Think of it as an "undisplayed" defaultTime.
