Like most countries, Britain has now moved to summer time. I changed my clock in OS X to the BST fine, and went into Windows. I noticed the clock in Windows was still behind, so I changed it to BST as well. When I booted back into OS X the time had moved ANOTHER hour forward! How can I stop the clocks messing with each other? This only happens when the time is +1 (summer) so it must be something to do with how the two handle time.
