The Client Console displays timestamps based on the time zone and clock of the server for which it is installed. Since all LogRhythm Cloud servers are configured to UTC, the timestamps for the last log message, agent heartbeats, and others will also be displayed in Coordinated Universal Time (UTC)
This cannot be modified as the Client Console does not have this configuration/display option. There are options in the User Preferences to modify the displayed time zone in reports and alarms. However, this does not apply to the rest of the Client Console.
