jboss has wrong time

Seems like a dumb question but I'm confused by this and haven't been able to figure it out.

My Jboss app server (4.2.2) running on my dev machine (ubuntu 810) is using the wrong time.

Basically all the logs etc show the time as being 1 hour behind what it really is. My system time and zone are setup pro开发者_运维技巧perly.

I also tried using -Duser.timezone=xxx switch, didn't change anything.

Sort of confused here ... anyone else ever seen this or know what could be causing it??

You might want to read DaylightSavingsTimeIssues on the JBoss Wiki. If your operating system time and local time zone are ok, look at the JVM level and try to update the TZDB (see Timezones, Daylight Savings, and the Sun TZupdater for the Java Runtime Environment (JRE) if you are using a Sun Virtual Machine).

If your problem is related to daylight savings time, then this page should be helpful. Check to see whether your JRE is up to date.
