Some features do not have time travel support (comment
            spotting and DHCP map at the moment). We also lack
            compatible SNMP data for the first day or so, so you'll
            only have ping data for the first day of TG15.
            It could take some time to load a specific point in time
            for the first time. See "About performance" under the help
            menu for more information.
            You can also step backwards and forwards in time, stop
            and start replay and go back to real time using keyboard
            shortcuts. See the help menu for an overview of keyboard
            shortcuts.
