The 4 hour time difference

Because Summer Time ended last weekend in Ireland and the UK, but does not end until this weekend here in the US, we are now in a week when the time difference between Boston and Ireland 4 hours, not the usual 5 hours. This can result in all sorts of confusion. It also means that the time difference from Boston to Ireland is only one hour more than the time difference from Boston to California. It makes Ireland feel more like the 51st state than ever.
