How does a user set a default time zone in QRadar?

To set a default time zone in QRadar, a user utilizes the User Preferences menu. This option allows users to customize their personal settings, including the time zone in which they wish to view logs and other data within the platform. The User Preferences menu is designed specifically for individual user configurations, making it the appropriate choice for adjusting settings like the default time zone.

Other options, such as the Log Activity tab, Admin tab settings, or dashboard configuration, do not provide the necessary functionality for personal user settings. The Log Activity tab focuses on viewing and analyzing logs rather than user-specific preferences. The Admin tab typically contains general administrative settings and configurations for the entire system rather than options tailored for individual users. Finally, dashboard configurations are concerned with the layout and content displayed on the dashboard, not time zone preferences. Thus, the User Preferences menu is the dedicated area for setting a default time zone.
