How to change the logging formatter in JBoss EAP 6?

Issue

• How to change the logging formatter in JBoss EAP 6?
• Is it possible to change the formatter in logging.properties in JBoss EAP 6?
• I want to add a date stamp into the logging in our JBoss standalone server. I added the below code to the JBOSS_HOME/standalone/configuration/logging.properties but it quickly reverted back after starting the server. Is there somewhere in the CLI or console to change this so it does not get overwritten?

**New:**
formatter.PATTERN.pattern=%d %-5p [%c] (%t) %s%E%n

**Old:**
formatter.PATTERN.pattern=%d{HH\:mm\:ss,SSS} %-5p [%c] (%t) %s%E%n
