Why use the "most accurate time source in the world"? The sender of the
signal from that clock does not know how long it will take to reach my
computer. It can only make an estimate which will rarely be as correct
as an atomic clock.

It's better than using the "most inaccurate time source in the world"

However, ever since XP, Windows has by default set its clock from an
atomic clock, an NTP server, with the travel time assumed to be half of
the round-trip time - which may occasionally be wrong, but is usually
considerably less than the internal precision of a PC clock. So that site
doesn't improve the accuracy of anyone's time knowledge.

Also anyone using GPS or mobile phone for time are using at least 4 "out of
this world accuracy" atomic clocks.

Fred makes a very good point.
The first time I checked, it said my computer clock was 0.5 seconds
fast.
I accessed the web page again 30 seconds later and my computer time is
exact.
It's not the most accurate website in the world.

Mmmm, it says my computer is 2 sec slow. It says the same for my weather
station.....which also gets it's time from an atomic clock. Odd or what?

I'm just a bit gobsmacked at all this pedantic concern about accuracy.
I freely admit that I'm a bit behind the times but it doesn't seem to impede
my travels through time one bit.
It would appear that my PC clock is 19 seconds slow.
(I can hear the sharp intakes of breath even now!
Well, in 19 seconds time.)
So what?
There are times when I don't even know what day it is.
With the world hurtling towards disaster, will it make much difference
whether it happens in 0.1 second or in 19 seconds time? I think not.

"They" don't know, so they halve the time for the round trip. The
uncertainty is vast compared to the resolution of an atomic clock; which
is why the whole thing is daft.

No. If two devices get their time from an atomic clock (or even the
same one) the time for the getting and the setting of the devices'
clocks can easily be two seconds.

Here's an example. I've set up a signature in my news reader but it's
not displaying it. There's obviously a box that I haven't ticked or
some piece of info that i haven't filled in somewhere but I'm damned if

My claim has not met with universal agreement. Let's try this instead:
If people at the back of a crowd push against the people at the front,
and people at the front get crushed to death, then it's the people who
did the pushing who are to blame for the deaths, even if they are
whining, self-pitying scousers.

Yes, but that has to be downloaded and installed.
And it's Windows only, as it eplains further down the page:

http://www.arachnoid.com/abouttime/#Linux

"But Linux, unlike Windows, is a civilized operating system, offering
the kinds of resources one should expect from an operating system meant
to meet your needs, not the needs of a very wealthy corporation. This
means Linux already knows how to synchronize itself with various kinds
of time servers, and it also knows how to synchronize local intranets.
This capability is innate and does not require any add-ons."

check the headers, though Mike's OS may be win7, he is using a pukka
newsreader rather than the Microsoft Mail thing that causes the
attribution problems.

You mean a bit like a rhinoceros? I think they are Klingons. The
Vulcans are the ones with slightly pointing-up ears. They follow
logical thought patterns which can sometimes lead to odd, even if
logical, behaviour. Whether that has any relevance to the OP I feel I
do not have either the qualifications or experience to comment. I can
only observe that
(a) when a hole is perceived to be getting deeper than necessary it is
better to stop digging
(b) when so many trains have left the station it is just possible that
the last one has been missed
(c) the time indicator on my laptop reads 21:14

I expect it is something like 1milli sec per 186 miles

Actual time depends where you are in space. Even the atomic clock
varies accordingly.

I have been reading this thread in disbelief...

Checked against my radio-controlled wrist watch, my computer time has
varied between two seconds slow and five seconds fast.

Yep. Computer clocks are never all that accurate. Keeping the clock at
the right time is a low priority task for the processor so if it's busy
doing other things the clock gets neglected. As you say, 'so what?'

Just one second.

Elapsed time can be measured to greater accuracy, possibly even to
microseconds, but not time of day.


I remember some old computer using a 'tick' which was synchronised to the
display, and therefore to the mains frequency, either 1/50 of a second in UK
or 1/60 of a second in US, but nothing that used 1/55 of a second.

Cheers Oliver, yes now that I think about it they are the pointy eared
ones (though that doesn't discount them from my list of cute in an
alien kind of way)

How does one calculate when a hole is deeper than necessary? Consult
Bernard Cribbens, perhaps? Though then you may be faced with the
dilemma that it really should be elsewhere anyway and someone will
start in about the whole shape thing too.
Aint life complimacated sometimes?

Here are the details. The IBM PC used an 8253 providing "ticks" at 18.2
Hz. 1/55 = 0.0181818... so I was close. The 8253 was used in all PCs
compatible with the IBM PC up to 2005, but I have been unable to
determine whether it was used with the same divider (but if they were
truly compatible, they must have). The HPET, ticking at at least 10
MHz, only appeared in 2005, and, in any case cannot be used by XP though
it can be used with Vista and Windows 7. What its fastest ticking rate
is, I don't know. I may look into the matter more tomorrow.
