How do I programmatically set the time zone in Java?

问题

I know I can feed VM arguments as follows

-Duser.timezone="Australia/Sydney"

Is there a programmatic way to do the equivalent? I would like the setting to be applied across the entire virtual machine.

回答1:

java.util.TimeZone.setDefault() can be used to set a default time zone to be returned by getDefault().
