I am in the UK and so currently on British Summer Time (BST) AKA "Daylight Saving Time" (DST). On October 26 our clocks go back one hour and we will then be on GMT (Greenwich Mean Time).
I use A+ and have the integration with Google Calendar.
My Google Calendar is set to UK time (Google calls this GMT:+00:00 London even though strictly we're not on GMT at the moment).
My WP install is on London time and is correctly working on DST at the moment, ready to change in a month's time.
Every March and October when our clocks go forward or back I find that my appointments get changed. It isn't easy for me to describe what happens because I have a lot of appointments and I think my administrator has already corrected some of them 'manually'.
But right now, for example, all my appointments for October 28 that were created by A+ are correct in A+ on WP but are an hour earlier on the Google Calendar. However, the appointments created on Google Calendar are correct and haven't 'moved'.
Does anyone understand what is going wrong? Has anyone else experienced this - and if so, can you describe the problem in better clarity than I can? Is it a bug or something I've got wrong in my set up?
