Nifi changed UTC time to CST time

Recently in use nifi This tool is used to synchronize data , The time found on the system during use is UTC Time , Time difference with China 8 Hours , and nifi The time of data scheduling is also based on UTC Time to schedule , Later, I began to consider how to change this time .
My side of the NIFI Yes, it is docker Installed , So the first thing I think of is docker The wrong time of the container leads to nifi The time is wrong , So I changed the time zone of the container , But after the time zone of the container is changed nifi The time has not changed .
Finally, another change was found nifi The way of time ：
modify nifi Of bootstrap.conf file , Add the following ：
java.arg.8=-Duser.timezone=America/New_York
take America/New_York Change it to Asia/Shanghai
Restart container ,nifi System time becomes Chinese time .
