The Windows clock bottom right-hand corner of your screen is normally updated automatically.
If this board is still displaying the old time on your PC please go to the User Control Panel and check that "Summer Time/DST is in effect" is enabled in "Board preferences". [Tick "Yes"}

Note that it's still possible to set older video recorders automatically by connecting them to a satellite channel such as Eurosport which still transmit a Teletext service. You don't need to subscribe to Eurosport to access the Teletext signal and you only need to connect long enough for the clock to adjust.
