A keen amateur horologist, Lord Tanlaw is a Fellow of both the Royal Astronomical Society and the British Horological Institute. In 2005, he introduced the Lighter Evenings (Experiment) Bill, which would move the United Kingdom’s time zone forward by one hour, to UTC+1 in the winter and UTC+2 in the summer, for a trial period of three years. Lord Tanlaw claims that this would reduce accidents in the winter as the evenings would be lighter, and has the backing of the Royal Society for the Prevention of Accidents. Opponents fear that it would have an adverse effect on people living in Scotland and northern England, where the mornings would be much darker. A similar experiment, known as British Standard Time, was trialled between 1968 and 1971 before being abandoned. The bill had its second reading in the House of Lords on 24 March 2006. The government had already rejected the proposal the previous year. Lord Tanlaw persists in pressing his case for a change of time zone. Most of his recent appearances in the House of Lords have been to argue for lighter evenings, which he does when there is only the most tenuous link to the topic being debated in the chamber. Such has his reputation become that other Lords are able to predict when the issue will be raised by Lord Tanlaw’s appearance in his usual seat on the cross-benches.
