following How to store date/time and timestamps in UTC time zone with JPA and Hibernate I want to set my application default time zone to UTC. My app runs on tomcat on a linux server along side some other apps. The server has other tomcat instances that run even more apps. Will Timezone.setDefault(tz) affect the other apps on the same tomcat instance? Will it affect other apps on other tomcat instances? Is it possible to set the timezone only for the app?

Simplified version of the code: foo.h class Foo{ public: void Foo(); private: bool bar; } foo.c Foo::Foo() { if(bar) { doSomethink(); } } In fact, by default it's not initialized at all. The value you see is simply some trash values in the memory that have been used for allocation.

Is there a method that will return a user's default browser as a String?
