Docker Java Application log time and container time inconsistency

1. The Docker container and the system time are inconsistent because the Docker container has a native time zone of 0 time zones, while the domestic system is in the East eight zone.
2. There is also a eight-hour time difference between the log time played by the Java application running in the container and the standard time of the container obtained through the Date-r method.
That is, the container time is consistent with the system time, but the deployed application and container time are inconsistent. Example of deploying a Java application in Tomcat.

Modify the container's time zone

CP  /usr/share/zoneinfo/asia/shanghai    /etc/localtime   

Modify Tomcat Java_opts

java_opts="$JAVA _opts-dfile.encoding=utf8  -duser.timezone=gmt+08"
