DST finished here at 3am on the Sunday morning, it was that night that my son was cut off at 8.30pm instead of 9.30pm. I've changed bedtime to 10.30pm and he tells me it's cutting him off at 9.30 now. I'll double check that for sure tonight and reply back. I have some learning to do on HomeShield I guess, I do thinks like "Reward" my child with an extra 30m and bedtime starts at the scheduled time anyway, so I guess I have to work out why that happens. Maybe "Reward" only works for time limits, not bedtime?

@David-TP, it's definitely still an issue, I have to have the kid's bedtime set an hour later than the real time in order to shut it off at my desired time. I have 3 kids with different bedtimes set, and for all 3 of them, their wifi is being blocked 1 hour before the bedtime I've set in HomeShield Pro.
