UK’s atomic clock ‘is world’s most accurate’
- An atomic clock at the UK’s National Physical Laboratory (NPL) has the best long-term accuracy of any in the world, research has found.
- Studies of the clock’s performance, to be published in the journal Metrologia, show it is nearly twice as accurate as previously thought.
Is the UK on GMT now?
The United Kingdom is not on Greenwich Mean Time (GMT) all year. During Daylight Saving Time (DST) the correct time zone is British Summer Time (BST). The UK observes DST from March to October every year. However, a lot of people aren’t aware of this, which leads to mistakes when they use timeanddate.com services.

Which clocks are the most accurate?
Atomic clocks are the most accurate time and frequency standards known, and are used as primary standards for international time distribution services, to control the wave frequency of television broadcasts, and in global navigation satellite systems such as GPS.
Which clock is the worlds most accurate clock?
Mechanical Clocks. Mechanical clocks were considered one of the most accurate clocks when they were invented,but not so much nowadays.
What is the most accurate time clock?
An atomic clock is the most accurate type of timepiece in the world, designed to measure time according to vibrations within atom s. NIST-F1, the United States’ standard atomic clock, is said to be so accurate that it would neither gain nor lose a second in over 30 million years.
