Methyl's link gives a comprehensive answer for everywhere. Briefly (to summarise) the whole of the EU and most of the rest of Europe change their clocks at 0100 GMT (the same as UTC) whatever time it is locally. So if we wanted to be precise we would alter them from 1am to 2am in the spring and in the autumn change them from 2am back to 1am.
Before we observed the EU times (I can't remember when this was but I think it was about 1980) we changed the clocks at 2am GMT (i.e. from 2 to 3 in spring and from 3 to 2 in the autumn).
As for recording TV programmes...this weekend I wanted to record a programme at 6 o'clock on Sunday morning. I correctly guessed that the TV station would still be operating on the old time but to be quite sure, I set the recorder to record from 5 to 7 (for a one-hour programme). Sure enough, when I checked the recording later, I found that the recording started at "5am" even though it was listed as 6am in Radio Times. If ever you want to do this on the night when clocks change (either way) always build this in as a safeguard.
