When talking about the time zones, it is hard to begin, since there are so many interesting facts about it. There are 24 zones and there is a 15 degree difference between them. Even though it looks quite simple to divide the planet into 24 parts, it is not always as simple as you may think. Therefore, the Daylight saving time also known as DST is used in North America, and also in some regions of Europe, South America, and there is a name for it – Summer Time.
In Brazil, for example it is not that easy to determine the time, since they are setting the Summer time by decree every single year and that is why in some states you can find them observing the summer time differently every year, and Brazil is one of those countries. That is one of the reasons why it is not that easy to tell time in these countries as it may be in some others. In Arizona, they are not following this rule at all, and they are not observing DST. But, at the same time there are some parts of a country which doesn’t observe DST, which do observe it, such as Navajo Reservation.
There is a law in Israel which says that every summer needs to last for exactly 150 days, which means that they have to set their clocks accordingly. Even though Greenwich time is the Prime time, and its center is in London, during the summer time, London is one hour ahead of the GMT time. You may heard soldiers in some movies mentioning Zulu Time, or letters A to M, and N to Y. That is because Z means Zulu Time which represents UTC or GMT. The letter J is not used since it represents the current time of the observer.
You have probably never thought of this, but do you know what time is it in space? When we say space, we are talking about the space stations with people inside of it, like the space station MIR for example. They are using the standard GMT time for the obvious reasons, since there are no time zones in the space.
Since it is hard to tell time in some of the parts of the world, that is why you have to go online and search for it yourself. Luckily, there are many time zone converters and that is why it is not that hard to find what you are looking for. It is interesting how many fun facts there are when it comes to this matter, and one of the fun facts is that when it comes to the GSM world map, it is completely different from the standard time zones as we know it. The list goes on, and the main problem everyone is facing with is the jet lag. It is so hard to adjust to it.
