John did all of our clocks before he went to bed. I couldn't remember whether my iPhone would automatically change and I needed to set the alarm to make sure Tom was up for his paper round so I looked online and found a comment that they automatically switch at 1am so seeing as it was half an hour away I read for a bit and it did change.
I'd have just taken a chance with it changing automatically normally but I know what Tom's like for getting himself up - or not getting himself up as the case usually is!
