World Clock & Time Converter (2024)

FAQs

What is the best time converter app? ›

World Time Buddy is a popular visual world clock, time zone converter and scheduler. Millions of people rely on our app and website to schedule calls, meetings and events! ▶ Convert time with a glance down the column of hours. ▶ Pick good meeting times (look for light tiles, representing work/awake-hours).

Atomic clocks deviate only 1 second in up to 100 million years.

If you move east from the prime meridian, add the appropriate time for each longitude and if you move west then subtract the time to calculate the time difference. Say, the longitude is 75 degrees east, then 75/15 = 5 and east means you add five hours, so the standard time will be UTC+5 or 5 hours ahead of UTC.

World Time Buddy (WTB) is a convenient world clock, a time zone converter, and an online meeting scheduler. It's one of the best online productivity tools for those often finding themselves traveling, in flights, in online meetings or just calling friends and family abroad.

The new JILA clock uses a web of light known as an “optical lattice” to trap and measure tens of thousands of individual atoms simultaneously. Having such a large ensemble provides a huge advantage in precision. The more atoms measured, the more data the clock has for yielding a precise measurement of the second.

Add the local time offset to the UTC time. For example, if your local time offset is -5:00, and if the UTC time is shown as 11:00, add -5 to 11. The time setting when adjusted for offset is 06:00 (6:00 A.M.).

To calculate the duration of time, you can draw a line with the start time at one end and the end time at the other. If the start time is not directly on the hour, add up the minutes to the next greatest hour. Do the same with the end time but to the next smallest hour. Add up the hours in between.

The International Earth Rotation and Reference Systems Service (IERS) measure Earth time, known as Universal Time, by watching the stars race past as the planet spins. They then combine this with International Atomic Time to get a final figure for Coordinated Universal Time.

The world's most precise clock is found in the United States. The clock was built by the National Institute of Standard and Technology together with the University of Colorado, Boulder. The clock is so precise no second is lost over the entire age of the Universe.

In 1967, a committee at the United Nations officially adopted UTC as a standard that's more accurate than GMT for setting clocks. UTC incorporates measurements of the Earth's rotation as well as averaged readings from around 400 atomic clocks around the world.

Which country is behind in time? ›

The country that is furthest behind in time is American Samoa, an unincorporated territory of the United States. It is located in the Pacific Ocean and is part of the U.S. territory of Samoa. American Samoa observes the time zone known as "UTC-11," which is 11 hours behind Coordinated Universal Time (UTC).

You can see that the most extreme time zones are +14 hours at Line Islands (Kiribati), and -12 hours in and around Baker Islands (US). Therefore, the maximum possible difference between times on Earth is 26 hours. That means that at 11:00 PM of a Monday in Baker Island, it is 1:00 AM of a Wednesday in Line Islands.

Currently the United States and its territories have 9 time zone boundaries: Atlantic, Eastern, Central, Mountain, Pacific, Alaska, Hawaii–Aleutian, Samoa, and Chamorro.
