Recommended public SNTP time servers
NIST Internet time service
The National Institute of Standards and Technology (NIST) Internet Time Service allows users to synchronize
computer clocks via the Internet. The time information provided by the service is directly traceable to UTC.
Table 13 contains information about all of the time servers operated by NIST. Please note that while NIST
makes every effort to ensure that the names of the servers are correct, NIST only controls the names of the
nist.gov severs.
