Why the time is way off?

The time in my Java web applications is way off the mark. For example, the time on the log4j message file is Apr 18 13:44 when the time on the Linux box is Apr 17 21:44. The applications use the same time data of log4j. There is not such issue in the development Window box, but only on the deployment Linux box. The applications don't change the time setting, nor the time zone. I have to ask whether it is possible that TC can be configured with different time set as its underlaid OS or not. Is a way to find out the time setting in a TC? I don't have a control of TC on the deployment box, btw.T

Any idea?
