In your example ‘Setting the Default Time Zone’ you set it to PST but the result was still printed in (translated) GMT. How can one get it to print in PST also?

use FastDateFormate from apache – for thread safe.

Thanks, SimpleDateFormat constructor and Locale.ROOT as parameter makes it works (same format string) !

Yes, SimpleDateFormat is NOT thread-safe, even if you synchronize externally, because the Calendar field in DateFormat is mutated when being serialized.
I recommend not using DateFormat and Calendar at all and instead use Joda-Time http://joda-time.sourceforge.net/ which is properly thread-safe, etc.

Is SimpleDateFormat still obnoxiously not thread-safe?

I have heard from many sources not to use this and use the Apache Date/Time libraries…
