You may have noticed that the times listed on posts have not adjusted to the clocks going back. The only way for members who registered before the clocks changed from BST to GMT is for individuals to change the setting themselves.
Go into your User Control Panel (near top left of page next to where it shows new messages)
Go to Board Settings
Find Summer Time/DST is in effect then change it to No
And that’s it!
A learning experience is one of those things that say, “You know that thing you just did? Don’t do that.” - Douglas Adams
