Unfortunately common sense is of no use in this case, at least as far as
ths Sun JDK 1.2.2 goes..
For parse() and format() it uses a Calendar object (originally defined in
DateFormat) for working on. Look at the code, it's truly frightening that
somebody would choose to write it this way.
Until yesterday I would have used static SimpleDateFormat objects in my
code too.. :o(
