We fetch a server clock and let you see

Webservers transmit their time in seconds unit, so without special treatment, the maximum error would be as big as 1 second. NKO Atomic Clock calculates a server time more than ten times in 1 second and seize the moment when the second changes. Thus we can minimize the calculation error as small as 0.1 second. Moreover, delays between our server and a destination server are considered so the accuracy of time increases.

NKO supports the HTTPS protocol and subdomains

Some servers use different servers over protocols or subdomains. You can get a desired result by specifying more details.

Information

# You need to tell us an exact server address. For example, some sites host differently by whether the address begin with WWW or not.

# Even if your computer clock isn't synchronized, NKO always will display correct time.

# If you click a numeric time error in the history view, the clock will use that measurement.

# The results can have quite much error if the destination server is under load balancing. Please refer to a variance in the server time history information.

# A particular service uses its own time clock, different with web servers' clock. in this case, server time guessing is not meaningful.
