Re: NSDateFormatter problems

Single-stepping through your code, I see that the default short format
on my machine is not
   %m/%d/%y
but
   %1m/%e/%Y
-- at least on my system, where I specified a four-digit year on short
dates in the System Preferences.

The culprit seems to be the numeral 1 in the %1m. It suppresses the
leading zero in output of month numbers.

Bug one: There is no "clean" format in the date formatter routines for
month numbers without leading zeroes, so the "precision digit"
workaround has to be used.

Bug two: NSDateFormatter apparently does not accept any string as
conforming to %1m.

I'll file this one with the Bug Reporter...
