For the most accurate time possible, you would need a direct connection
to an atomic clock! Over the internet, the best you can hope for is to
be within five or ten milliseconds of the correct time.
Servers close to you are usually the best. If you configure ntpd to use
four servers it will select the best of the four.
If you can obtain a GPS timing receiver you may be able to get within a
few microseconds of UTC.
