Let's say you live in New York but you have family members living in London. In that case it's very important for you to know how to tell the time in both cities. Whatever reason you may have for needing information on the time in two different locations, it's good to know that there are so many free online world clocks out there that could help you out. All you have to do with a world clock is to input the date and the exact time (hours and minutes, and remember to state whether it's AM or PM) at your own locality, and then the city or country name whose time you'd like to get to know. Usually, you have to choose from a list of different countries. In case you don't see the particular country you're interested in, you may choose a nearby country that has the same time zone as the particular country you need.
Some relevant terms that you might encounter:
- Daylight Savings Time. Some countries observe Daylight Savings Time (DST), wherein the people simultaneously adjust their clocks to make it one hour advanced, or to make their time "spring forward". DST typically begins during the spring time, as an effort to conserve energy by taking advantage of the longer daylight hours. DST typically ends during autumn, when people turn back their clocks one hour to return to Standard Time. There are many countries that follow DST, including the United States, Canada, and countries of the European Union. When you want to find out the time in these countries, make sure that the international clock you're using adheres to the DST when appropriate.
- Abbreviations. GMT means Greenwich Mean Time; this marks the starting point for every time zone in the world. Currently, GMT is known as UTC, or Coordinated Universal Time. The UTC is considered to be the standard for differentiating time zones from one another; like for example, Pacific Daylight Time could be defined as UTC-7 hours. Different time zones too have different abbreviations, such as Central Standard Time (CST) for Australia, and Western European Daylight Time (WEDT).
- Different Time Zones within the Same Country. Some countries have different time zones, and one example is the United States (which has 6 time zones). So if you want to find out the time in the US, you'd have to know which particular time zone you'd need or at least the name of the relevant city or state. Take into consideration also if they are currently following DST (see number 1).
- Desktop Clock. If you would like to always be aware of the time in another country, then you could opt to install a desktop clock onto your laptop or personal computer. One available desktop clock is the Sharp World Clock. You can choose to install it in its digital or analog version, and it has several features such as clock calendar capability, and available designs. You could also have a screensaver clock for viewing every time your computer goes idle.
- Atomic Clock. An atomic clock ensures reliability and accuracy of a clock to 0.08 seconds, using microwave signals emitted by electrons. There are many atomic clocks that you can download for free via the Internet.
There you have it! Those are just some of the key tips you'd need when using a world clock converter. Good luck!
