Lots of responses, from lots of people, most told me what I already
knew. That time on the system is kept in UTC style so time never
actually changes just the users perspective of time. Two people told me
the correct answer that I was looking for, but both were unsure, so I
couldn't take their answer as gospel.
I guess I phrased my question incorrectly. I should have said "During
the change from Daylight savings to GMT what does a running process
perceive the time to be?". I followed some advice which was to
experiment and see, which is what I was trying to avoid. The result was
that the process saw the time jump from 2:00am back to 1:00am.
Thanks to all those who replied.

Original Question
Quick question about how unix actually changes the time at end of BST.
The line from the /etc/timezone/sources/europe is:
Rule GB-Eire 1996 max - Oct lastSun 1:00s 0
GMT
Does this mean that at 01:00am on the last Sunday of October, that the
system spends 1hr being 1:00am. Or does it mean that at 2:00am it sets
the time back an hour, which presumably would be bad.
Thanks
Robert.
