Most Freeview Approved devices update automatically for Daylight Savings, so you won't need to do a thing.

If you’ve changed the time settings on your TV, box or recorder or if you’re using an older set top box or recorder, such as the Zinwell/DSE satellite receiver, you need to manually set your clock to daylight savings time.

If you don't, the actual on-air times for programmes on your TV will not line up with what's showing on your programme guide; or if you want to record something, it may not start at the right time as the clock is out of sync.

To change the time on your TV, set top box or recorder

Go to Menu (or Settings) > System Configuration > System Setting > Time then change "Summer" to ON or OFF.

Note: The instructions above are general guidelines, though most device menu structures are similar, it's always best to refer to your product manual for device-specific instructions if required.  You can search for the brand of your TV, box or recorder here to find support contacts.
