This is a region on Earth that keeps the same standard time. Offsets from UTC are written in the ±: format. A UTC time offset is the amount of time subtracted from or added to UTC to get the current local time for a specific location. Within this implementation most nations began to use the UTC standard when defining their zones instead of the former GMT definition.
Since 1972 all official services have broadcast radio time signals synchronized to UTC, a form of atomic time that includes leap seconds to keep it within 0.9 seconds of this former GMT. This time keeping method is less exact than the UTC because the rotational period of Earth is not perfectly constant and the duration of a second would vary if calibrated to a telescope-based standard like GMT.
GMT was calibrated to the mean solar time at the meridian passing through the Royal Observatory in Greenwich, UK. Greenwich Mean Time (GMT) is an older standard, adopted starting with British railroads in 1847. This represents the modern civil time and has been defined since January 1972 to follow the International Atomic Time (TAI) with an exact offset of an integer number of seconds. Coordinated Universal Time (UTC) definition Also knowing important world time zones can help you make connections between time and geographical position of certain countries making it easier for you to remember where some place is or simply check how the daylight savings time system works in other places. You can even find yourself in the situation to make phone calls or conferences abroad and you need to schedule them at an appropriate time for all the participants and the biggest the time difference is the harder will be for you to manage things without knowing exactly the local time there. Maybe you are going on a vacation in a foreign place and want to know exactly the local time there or you need to call someone overseas. Surprisingly enough there are many situations in which you can find yourself in need for a quick check of an international time in a given place and the easiest way is to use such a tool. Why you may need to use a time zone converter? This is the rule of thumb for any international conversion: "time in zone B" = "time in zone A" − "UTC offset for zone A" + "UTC offset for zone B". Once you have selected the region the second selection for location will display the countries or the cities in the region you chose in alphabetical order for you to find the desired place easier.Īs you press calculate the time zone converter will find your locations in a complex database of the world time zones, check whether it needs to take into consideration the existence of a daylight savings time and will then calculate the time zone difference between your two locations and return you with the exact time in the second place you chose. You can choose from Africa, Asia, Australia, Caribbean, Central America, Europe, North America and South America and for each region you need to decide if you prefer a country or a city. In each of the two lines you first need to choose the region in order to narrow your choice. Below are two lines in which you need to choose the starting point for the international time conversion and the location for which you want to find the corresponding time. The first two fields are the current date and time and you can change according to your needs. If you take a look at the form above you will see that all the fields in the left column can be modified and that the right column is the area in which the results will appear once you make your choices and press calculate.
#Time zones time converter plus
It covers the international time in all the countries in the world plus some of the most important dependent territories and also takes into account daylight savings time (DST). All you have to do is choose the region, be it from Africa to South America and whether you want to pick a country or a city in that region to use. This is a time tool that is based on the time zone map of the world and finds the time difference between any of the locations listed in the form. How does this time zone converter function?
