      "note": "SKCC PRINTS TWO UTC TIMES AND THE CONTEST HAS ONE LOCAL TIME. 2000Z from November to March and 1900Z from April to October are both 2100 in central Europe: CET is UTC+1 and CEST is UTC+2. So this is not a contest that changes its hour twice a year, it is a contest at nine in the evening that Europe's clocks move around, and it is recorded the way the sponsor means it -- `timezone: Europe/Berlin` with wall_clock times, exactly as the ARS Spartan Sprint is recorded in New York.\n\nTHAT READING IS TESTABLE AND IT PASSES ON THE MONTHS THAT DECIDE IT. Europe changes clocks on the last Sunday of March and of October, and the first Thursday of both months falls on the near side of the change: March is still CET and resolves to 2000Z, April is CEST and resolves to 1900Z, October is still CEST at 1900Z, November is CET at 2000Z. All four match SKCC's own table, which is what makes this one rule rather than two.\n\nEncoding it as two records split by month -- winter and summer -- would have produced two entries with the same name and hidden the reason. Encoding one UTC time would have been wrong for five months of the year.\n\nStraight keys, sideswipers and bugs only: no keyer, no keyboard. That is the club's whole premise rather than a category.\n\nThe fifteen-minute QRS extensions at each end are not in the window: they are an invitation to slow operators rather than part of the scored period.",
