Comment (by danielbachhuber):

 After talking this through time and time again, @viper007bond and I feel
 reasonably confident that DST should be abolished.

 The bug is most likely that 1:23 am occurs twice in London on 2015-10-25.
 `DateTime` doesn't know how to distinguish between them when doing
 relative time conversions so it assumes the later one. It could pick the
 correct one if it knew the UTC time.
