If your server is running in one timezone, but you want to have log messages be printed using different timezone, here is a simple solution:

1. Add log4j extras to project classpath (maven GAV is log4j:apache-log4j-extras:1.0)
2. In log4j.xml use EnhancedPatternLayout, specifying required timezone for logging purposes (see example below for EST TZ)

<appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender">
    <param name="Threshold" value="TRACE" />
    <layout class="org.apache.log4j.EnhancedPatternLayout">
        <param name="ConversionPattern" value="%d{ISO8601}{EST} %-5p [%t][%c:%M(%L)] %m%n" />
    </layout>
</appender>

In this example, log messages will be printed using EST regardless of your server timezone.
