Port 123. And... I don't know about "best", but I use time.nist.gov with no
issues.

What port is used for time sync and what is the best internet time

There was a time, not so very long ago, when at every tolling of the hour by
Big Ben, the British Ensign was being raised at dawn somewhere in the world.

Today, with every passing second marked by the National Institute of
Standards' atomic clocks (time.nist.gov), Windows is booting up, often for
the fourth time since dawn.

Inspiring. I'll change my boot up screen to a Union Jack ;)

Using stratum 1 time servers is not a polite thing to do to the time server
operators. You can usually get away with a lower-stratum time server, many
ISPs offer time servers that are within a second or less of official time
with a much lower ping to you on the same machines as your DNS servers.
The default Windows time server (time.windows.com) is Microsoft's way of
helping spread the load for time sources like NIST.

Keep your message writing preferences to yourself. I'll use the method I
prefer for each message.

Polite? Geeze.

Haven't you heard all the issues with time.windows.com? There is a constant
stream of "hey, time.windows.com isn't working for me". I use what works. If
they don't want me to use them they won't make them available to me.

By polite, I mean it's wasteful to bandwidth and increases the inaccuracy
due to network lag. Using a time server more than a stratum above yours is
considered to be a bad thing by NIST and anyone who knows anything about
network time.

That doesn't mean it's the only alternative time server out there. Like I
said, odds are your ISP operates time servers on the same machines as their
DNS. From the prospective of which is best for NTP time distribution is
concerned, these would be the correct time servers to use as they would be
much closer to you (as measured by ping and traceroute) than the overused
stratum 1 clocks.

In an ideal world, NTP would be one of those things you couldn't turn on if
you didn't have the know-how to play nice with it.
