Online Clock

Stay tuned with getdatetime.com, the exact time services that delivers the most precise current time accurate to second and millisecond depending on user's location.

A bit of History

Knowing the exact time was quite a challenge for our predecessors. People used sundials, sand clocks, and other inventions to stay in touch with the current time. However, ancient devices failed to deliver the desired accuracy considering several minute errors in every 24 hours. Humanity craved for something more precise. The struggle resulted in the invention of first ever mechanic clocks back in year 725. The new invention made a time revolution with minimum errors ranging from +40 to -20 seconds every 24 hours.

  • In 1957, quartz clock made its debut combining mechanic and electronic technologies. The first ever electronic clocks had mechanic hands featuring improved accuracy with some slight errors of only ±15 per month;
  • The atomic clock appeared to be the first ever standard for the most precise timing with zero errors. It was invented back in 1955 and it is still in use today. The key benefit of the atomic clock is the close to none error of ~1 every 100 million years;
  • Optical lattice clocks boast yet the highest level of stability and accuracy. They are three times more precise if compared to atomic version. The error is minimized to ~1 every 300 million years.
