ASATRUEJET-SETTERYOUWILLUNDERSTANDTHATKNOWING the time where you are, where you are going and where you have been can be a real challenge. Time is essential to travel: aircraft slots are scheduled to the minute and it’s vital to know when to call your wife in Los Angeles, make dinner reservations in Baku and contact your offi ce in London. Trying to do all that with an ordinary, single-time zone watch is a headache, involving mathematics and mental gymnastics not so easily accomplished when jet-lagged. Th at’s where multi-time zone watches, also known as GMT/UTC, dual-time or world-time watches, come in. Th ese watches display at least two time zones, doing all the complex calculations for you, meaning the hardest decision you have to make is which one to buy. Before the advent of standard time in 1918, every city and region in the US operated on local solar time, independent of any other city. Noon on the clock was when the sun hit its zenith wherever you were – but that moment changed with your longitude. So when it was noon in New York City, it was 12:12pm in Boston, Massachusetts; 11:30am in Cleveland, Ohio; and 11:14am in Indianapolis, Indiana. In a metropolis like New York, local time could vary as much as a minute or more between the east and the west side of the city. Sun time even diff ered by about 30 seconds between the two ends of the San Francisco–Oakland Bridge. PRIVATSELECTION Clocking In Want a goodnight chat with the kids in Cleveland when you’re doing business in Bombay? Keith W. Strandberg explains how you can time that bedtime call to perfection wherever you are in the world with a multi-time zone watch Th e US government offi cially adopted standard time on 19 March, 1918, just as Great Britain had given GMT the force of law in 1880. Within a decade, most of the world was keeping time by this system. In 1972, the majority of the world adopted Coordinated Universal Time (UTC) and now offi cial time zones are indicated by +/- UTC, rather than GMT. While that plus or minus usually refers to a diff erence of whole hours, there are parts of the world that have fi nessed the system into fractions of an hour. Newfoundland, India, Iran, Afghanistan, Venezuela, Burma and the Marquesas as well as parts of Australia use half-hour deviations from standard time, and some nations such as Nepal, and some provinces, like New Zealand’s Chatham Islands, use quarter-hour deviations. Th e United States has nine standard time zones, the same now as Russia, which used to lead the world with 11 zones across its 2,000km until it simplifi ed them two years ago. Two of the world’s largest countries, China (which should have fi ve time zones) and India, have but one time zone. When’s lunch? Well might you ask. With a world time/dual time/GMT watch, you have a much better chance of mastering the time zones, no matter how many you cross. Unfortunately, your watch can’t help you with jet lag. For that, you’re on your own.
