How to change the time zone in the Email Security.Cloud portal.

By clicking the Profile icon at the top right of the portal, you can choose a time zone. This setting does not reflect in all tools, however. The main use of this setting is to set the time zone for the custom and scheduled reports for your portal user. (The reports in the Reports menu at the top of the portal.)

There is no option to change all time stamps and displays in the portal to a specific time zone.
