Glassfish console log timestamps

By default glassfish does not add timestamps to console logging messages and that allways leaves me wondering wether I'm looking at an old message or a new one.
To add timestamps edit $GLASSFISH_INSTALL/glassfish/domains/domain1/config/logging.properties
Replace domain1 with the domain your domainin the above,  if you are not using the default domain.
change:
java.util.logging.ConsoleHandler.formatter=com.sun.enterprise.server.logging.UniformLogFormatter
to:
java.util.logging.ConsoleHandler.formatter=java.util.logging.SimpleFormatter

The default format is fine for me, but you can customize the format using:
java.util.logging.SimpleFormatter.format="your %format string"

The javadoc contains some format string examples.
Then (re)start the server.

Java logging toolkit levels mapping

A comparison of the logging levels (or methods) in different logging toolkits. I omitted the ALL and NONE levels.
