JDK9 changes to Date?

[Jochen Theodorou]

That means the US locale cannot understand CET as timezone then?

And... it assuming that TimeZone.getTimeZone('Etc/GMT') returns the GMT 
timezone, it means the short format for a date changed from using 70 for 
the year to 1970? Or is that CLDR related as well?
