Mám pocit, že táto charakteristika nijako nezostarla. "Deratizér na novinárske krysy." :-)

Why ISO date norms sows fear in hearts of developers? Let's see what week number it is on Jan 1 and Dec 31 of various years (2012 is my personal winner - and yes, norm is good, dates and weeks are simply difficult):
Year 2000 starts with week 52 and ends with week 52
Year 2001 starts with week 1 and ends with week 1
Year 2002 starts with week 1 and ends with week 1
Year 2003 starts with week 1 and ends with week 1
Year 2004 starts with week 1 and ends with week 53

"Good" old Java APIs always full of surprises. On Java 8 I'd use something like LocalDate.of(2014, 1, 1), I needed the same default on Java 7, so I - naturally - used new Date(2014, 1, 1) when the provided date was null. To my surprise my default had much higher millis value... something fishy is going on. One look to the API says: @param year the year minus 1900

Minus 1900? Well, ... there is hardly anything that may explain this reasonably. Sure, it's deprecated. But it will never be gone in the sacred name of compatibility (or other *bility?).

Many months later it is still there, so I added support request:

I guess it was in vain, I didn't know this forum is so active that any post scrolls away from the first page within ~50 minutes! :-)

Maybe I'll start blogging on GitHub, their markdown is way more reliable...

Ok, so this really got me :-) it pays off to go all the 20 mins, and actually, it's not that hard.
