David Malone (one of our members, I believe) gave a talk the other day: "It is one hundred years, today, since Ireland own time zone came to an end and moved to use the same time as Great Britain." See: https://twitter.com/dwmal1/status/782156281440264192 The slides: http://www.maths.tcd.ie/~dwmalone/p/dunsink2016.pdf Wish I could have heard the talk!
