Thanks - I guess that it picks up the time from the signal but, as you say I shall check it when I get back Sunday afternoon and in the meantime allow for all eventualities when it is coming on to record the GP.
I have a Wharfdale Freeview/PVR and the time updates itself. It gets the time from the aerial as VCRs used to, so you should be OK as long as the programme you want to record doesn't happen when the time changes at 1am.

No, a digital signal transmitted as and when necessary.
On the same principle as that of Ceefax/Teletext, which is why using the analogue Ceefax time display is extremely accurate for setting your watch etc (the Freeview version is a second or two behind due to the conversion required).
