I have a customer that would like to set up APM to display GMT, regardless of the local timezone. I was able to get this working on java web start, but not yet on the Web View.
Instructions below..
Open the file <Enterprise Manager>/product/enterprisemanager/plugins/com.wily.introscope.workstation.webstart_10.1.Eval/WebContent/jnlp/workstation.jsp
Locate the property.. timezone, and set it thus: <argument><%="timezone"%>GMT</argument>
Here's a picture..
If anyone has any ideas "how to do" on Web View. Please contribute!
