If the Applications Manager Plugin time is not in sync with the local host time, follow the steps given below:
1. Open the startApplicationsManager.bat file (For Windows) or startApplicationsManager.sh file (For Linux) present under the <OPM_Home>/AppManager directory.
2. Make changes to the user.timezone parameter.
3. Based on the difference in time or the time offset, modify the -Duser.timezone parameter.
For example:
From:

-Duser.timezone=CST
To:

-Duser.timezone=GMT-0600
4. Restart OpManager after applying the changes.
