Java's SimpleDateFormat can be set not to allow for lenient
parsing. Unfortunately NSTimestampFormatter lacks this ability.
I have created a subclass of NSTimestampFormatter which for parsing
uses an instance of SimpleDateFormat to create a Date which I then
convert to an NSTimestamp
I was going to write the same thing. I have found numerous issues
with NSTimestampFormatter, with formatting some symbols as well as
parsing. It looks like we have arrived at the same solution.
IIRC SimpleDateFormat is not thread safe. Oh joy!
I noticed that as well. That could be an issue for how I usually use
them (one instance cached at the application level). I will have to
look and see if it is safe to use like this if none of the set...
methods are called.

OK -
Now I am trying to validate dates. I hate dates. I especially hate
java dates, but I digress.
So now I have this little wizard component that asks for a date.
It has a date formatter.
However, someone could type in 13/33/09 and it will take it,
albeit change it to something else.
What is the best way to ensure a proper date is submitted or else
messaged back to them?
Thanks
