= JBOSS HowTo Set timezone Tags: [[JBOSS]] [[HowTo]] Some JBoss AS servers have failed to account for daylight savings, even though the system time and timezone information is correct. In this situation, starting the JBoss AS by using `run.sh -Duser.timezone="Europe/London" -b 0.0.0.0 &` seems to resolve the issue. Putting the option in JBoss run.conf file does notwork, although it is shown in the logs as being passed as a runtime option to the JVM. The option must be passed explicitly in the command line call to run.sh in order for JBoss to correctly start in the correct timezone. [[BackLinks]]
