Time.is
The service shows the exact time.Shows the error of our system clock.
The most interesting is that it shows an approximate dissynchronization of your computer clock with international atomic time, also shows the time in 7 million places of the world and compares time in different places.
Additionally, there are a number of nice bonuses: a calendar with the week number and the day's ordinal number, a time reference for sunrises and sunsets for each locality, integration with Google Maps, widgets for third-party sites. There is even a special design for Fully Screen mode in the browser.
And note that the appearance of a new second on the Time.is server occurs just at the beginning of this second.
Some operating systems do not even know how to synchronize computer time with this accuracy.
