The default timezone of a Sun JVM is determined by user locale settings.
If the runtime can't determine a sensible timezone from those it
defaults to GMT, which is 3hrs off from Brazilia time, i think.
Looking at the source of TimeZone it uses the following system properties:
user.timezone
user.country
java.home
If user.timezone is not set then a native call is made using
user.country and java.home. I'm not sure what happens for a
multi-timezone country like Brazil ;)
So you could:
1) pass in the user.timezone system property to the runtime.
2) Set your servers default timezone in code:
TimeZone.setDefault(TimeZone.getTimeZone(id));
where id is one of:
Brazil/DeNoronha
America/Sao_Paulo (probably the one you want or maybe Brazil/East)
America/Boa_Vista
Brazil/Acre or America/Rio_Branco
Are you running Tomcat as a service? If so, you may also want to check
that the regional settings for the user running the service are also set
to Brazilia.
I would also check what is actually being determined by the JVM. Do
something like:
System.out.println(TimeZone.getDefault());
System.getProperties().list(System.out);

Hi everybody
We have a Tom Cat application Server 5.0.19 running in a Windows
2003 with a Sun JDK 1.4.2.
We are having problems with time of our Applications . The time is
correct under SO but we have 3 hours of difference in the applications (+3).
Our offset time is Brasilia -3:00 in the Windows 2003 and Regional settings is
Portuguese, Brazil.
The method TO GET SYSTEM TIME is new Date()
Any suggestion, How we setup server parameters or application (JVM) parameters
to solve this problem?
Thanks a lot in advance
