I observed that my system (opensuse linux) was in a timezone GMT. In server.log of JBOSS the entires showed me date with a time lag of 5hrs for any current activity. I restarted my jboss but still the logs entry showed me 5hrs time delay.I then changed my timezone to EST and then back to GMT and restarted the JBOSS. This time the entries got corrected to OS time. Can anyone tell me reason behind this? Can the solution can be achieved without restarting the JBOSS?
