This is a bit less convenient than having a watch with an independently set local time hour hand, which you find on watches like the GMT-Master II, and it's the reason James coined the term "caller" for such watches – they work better if you're wondering what time it is at a place you call frequently from home. The other option is to re-set the local time to Geneva time, correct the date if necessary, and then re-set the 24-hour hand to the correct hour for New York. This, however, means the time display for the whole time you're in Geneva will be a bit counter-intuitive to read – you'll be reading the hour in Geneva off the 24-hour hand, and moreover, the date will not switch over at midnight Geneva time, but rather, six hours too late, because it will change over at midnight in New York. You can re-set the 24-hour hand to Geneva time and leave the hour and minute hand as they were, showing the time in New York. If you're traveling from New York to Geneva (today, as I write, the time difference is six hours, with Geneva ahead), when you land at GVA, you have two choices. In 1879, Scottish-born Canadian engineer Sir Sandford Fleming proposed the division of the world into 24 standard time zones, and by 1900, most countries had adopted some form of standard time, which gradually evolved into the system we know today. This time standard used GMT across the entire rail network. This meant, of course, that every town and village separated by longitude had a slightly different time, which didn't matter very much at all until the invention of the railroad – the first standard time was so-called Railway Time, which was adopted in 1840 by the Great Western Railway in the UK. Each time zone follows a standard mean time across the entire time zone prior to the development of standard times, the time was simply the local solar mean time. The multi-time-zone watch is an interesting complication – unlike many other complications, such as the moon-phase and equation of time, and even the perpetual calendar, it is not based on recurring natural events, but rather on an invented convention, which is the division of the world into time zones.
