I tried posting this to .programmer, but didn't get any answers so I'm
trying here.

I've been working my google fingers to the bone over this one, as well as
writing lots of experimental code.

In Java 1.4 JFormattedTextField:

1. Why doesn't the date formatter act like MaskFormatter and automatically
put the separator character as you type? Is there a way to change that?

I'm getting the date formatter using
dateFormat = DateFormat.getDateInstance(DateFormat.SHORT);
DateFormatter df = new DateFormatter(dateFormat)
JTextField startDate = new JFormattedTextField(df);

2. Is there a good way to input HH:MM:SS durations rather than dates? I'm
using a MaskFormatter, but of course it doesn't stop you from entering
from entering a duration of 55:66:77. I suppose I could use an
InputVerifier? I though about using a DocumentListener but I don't see
any way to refuse to take input if they enter a digit greater than 5 in
the 4 or 6th positions.

3. Going back to DateFormatter again, is there a way to make it stop
taking invalid dates? I can put 99/99/2005 into one and it returns a date
of 6/7/2013. I'd rather it refused to take it, preferably interactively
rather than waiting for the focus lost event.
