The daylight saving exercise aims to avail more daylight in the evenings by advancing the clocks by an hour. Apart from the fact that, even in the colder countries, studies have proven that the advantages claimed are doubtful, in a hot country such as Pakistan the disadvantages clearly outweigh any claimed benefits. In the first place, farmers the world over are not in favour of daylight saving and their work is directly related to sunlight. This is especially true of a country such as Pakistan, which has agriculture as its backbone. Also, with our low literacy rate, a great confusion persists throughout the year as most common people, whether in rural or urban areas, continue to try and relate the 'new' with the 'previous' time. In the overall urban work context, letting off people early into the very hot summer afternoons will surely not encourage them to head for shopping or to indulge in leisure activities, which most of them cannot even afford in the first place. Amongst some of the other disadvantages, travel schedules are directly affected, the sleep cycle is disturbed leading to potential health problems in citizens and the shift in the prayer timing does not easily reconcile with the office lunch breaks, often leading either to a very late lunch or a net reduction in working time. -M.A. RABBANI, Gujranwala, via e-mail, April 8.
