About August 23,time signals were first transmitted by telegraph from the Royal Observatory, Greenwich. Some British clocks from this period have two minute hands—one for the local time, one for GMT. The problem of differing local times could be solved across larger areas by synchronizing clocks worldwide, but in many places that adopted time would then differ markedly from the solar time to which people were accustomed.

On November 2,the then British colony of New Zealand officially adopted a standard time to be observed throughout the colony, and was perhaps the first country to do so.

This standard was known as New Zealand Mean Time. Each railroad used its own standard time, usually based on the local time of its headquarters or most important terminus, and the railroad's train schedules were published using its own time.

Some junctions served by several railroads had a clock for each railroad, each showing a different time. Dowd proposed a system of one-hour standard time zones for American railroads aboutalthough he published nothing on the matter at that time and did not consult railroad officials until In he proposed four ideal time zones having north—south bordersthe first centered on Washington, D.

Dowd's system was never accepted by American railroads. Allen, the editor of the Traveler's Official Railway Guide.

Jet lag is also compounded by the fact that long hours spent on a plane can cause you to sleep too much, or not enough, possibly at the wrong time of day relative to where you departed from.

But that only works within about 4 or 5 hours difference. Recovering from jet lag is a process that, well, takes time. A rule of thumb is that you recover about 1 hour difference per day. You may find that on your way out, you are fine after just a couple of days, but you will really notice the recovery period on your way home, particularly if you didn't stay long enough to fully adjust to the original time difference.
