Herostratus as orbitmic points out this is almost certainly a typical miscalculation. After all it is October month and European Summertime ends Sunday 29 October. This happens every year in the month before summer/winter time changes. To confuse you even more SYD changes to Summertime Sunday 1 October!

It is also interesting to note that at least until two years ago the IFE on the B787 showed arrival time at a destination in UTC not local time. This would have the reverse effect so you can be sure that this can be attributed to human error.
