2 minutes to spare

Another commuting day today - on a beautiful clear, crisp morning. As the escalators lofted me up out of the depths of Edinburgh's Waverley station I looked up to see this stark contrast of the new roof against the architecture of the Balmoral Hotel.

Did you know that the Hotel keeps its clock deliberately 2 minutes fast? It looms above the station and is visible from all directions, so passengers will see the clock and start hurrying for their train , and then be pleasantly surprised to discover they've got 2 minutes to spare.

There's only one time every year when the clock is deliberately and temporarily set to the "correct" time. When do you think that is, and why?

Meanwhile, welcome to FillGap who just joined the ranks of blippers. I'm looking forward to sharing this adventure with you.
