I had like to set it to JST (UTC + 9). We have set two things to achieve this.

1. I set the OS time zone to JST
2. I set -Duser.timezone = Asia/Tokyo to CATALINA_OPTS
3. Changed database timezone to Asia / Tokyo

    I confirmed that the above settings are reflected.

At this point, it has been confirmed that the time zone of the time stamp attached by the log4j logger is JST.

The main subject is from here. The following logs include a time stamp in the Pega application log.

$CATALINA_HOME/logs/pega/PegaRULES-ALERT.log

To clarify the problem, I added a time stamp to the beginning of the format separately on the log4j side .

• log4j config file: $CATALINA_HOME/webapps/prweb/WEB-INF/classes/prlog4j2.xml
• PegaRULES-ALERT.log format: %d{ISO8601}{GMT+9} %m%n

I tried to output the log in this state. Below is the result

pegauser@arc-pega-web-686df7dcc4-mtxqn:/$ head -n 1 $CATALINA_HOME/logs/pega/PegaRULES-ALERT.log

Unfortunately, the log added by log4j is JST(UTC +9), but the application log is still UTC + 0....

This Pega is running in a container on an Openshift cluster. The version will be 8.5.2
