Re: java.util.Date

I don't think it's your fault, Max. The docs should talk about that internal Calendar instance. Knowing things like that .oO( Hrm ... if it just has a single internal Calendar instance, it's probably doing modification to it on-the-fly ...) is quite important! If the only thing involved were the format, I think your apporach of moving things to a static initializer would have been the way to do it. Sounds like that's not the way to do it though :-(

That's exactly as I understood javadoc. *formats* are not
synchronized. Since format is applyed in static code I suggested to move
SimpleDateFormat creation there. Seems I was wrong. That's javadoc
ambiguously.

Sorry all guys for confusing you.
