The Time Picker on the Palm is (in my not-so-humble opinion) the best way of selecting a time on a handheld device. Here's an example from setting the start and end time for an event:

To set a time, click the desired hour and minute, or type the desired type. It's very fast and efficient.

I'd like to see something like this in DejaOffice in all places that permit time entry.

As an added bonus, I'd like to have a popup calendar available when selecting a date for anything. Again, this is much faster than the scroll widgets that are currently in place.
