Check out the EnhancedPatternLayout in the log4j extras companion, http://logging.apache.org/log4j/companions/extras/. It is an enhanced version of PatternLayout that is usage-compatible. Basically, add log4j-extras.jar to your path, change the Layout class to EnhancedPatternLayout and use a pattern like %d{HH:mm:ss}{GMT} or whatever any other recognized timezone in the second set of braces.
Performance of SimpleDateFormat is a significant issue. PatternLayout has an independent implementation, EnhancedPatternLayout wraps a cache around SimpleDateFormat to avoid calling it repeatedly for timestamps within an interval. http://logging.apache.org/log4j/companions/extras/apidocs/org/apache/log4j/EnhancedPatternLayout.html --------------------------------------------------------------------- To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
