Clock runs way too fast

My computer clock is running 1 minute fast every three hours. It syncronizes
at most once a day at 'nist1-ny.WiTime.net'. The two other sites were always
giving errors when trying to syncronize.

Is there some way to syncronize much more frequently? Do I need to use
another site?

Thanks

it use to be that if a
clock seemed to be runnnig
away with the time, then
the likely cause was a failing
battery.

Why? The synchronization takes place once a week by default. Once a day
means that you're either running unnecessary third-party software or
that you've already changed the default interval by a registry tweak
unless you synchronize *manually* once a day.

Nope. You need to know the culprit since this problem is caused by poor
software running in the background. Norton/Symantec crapware for
instance is notorious to cause that problem, just one example:

"System clock loses accuracy under Windows XP after installing Norton
AntiVirus 2002"

Sounds like a out of spec crystal on the motherboard. But here is the
frequency setting.

Nice one Bob! But 99% of the time, a fast running clock means the
CMOS/Setup/Clock battery is running low. As the lower the voltage, the
faster the clock runs. Although the fanciest syncronizer in my mind is
the free Dimension 4. It shows a history and everything.

his response is a pretty good one but
beyond the scope of mortals.

if i recall the formula is something like
when Voltage = Resistance x Current.

so if v decreases it is likely due to r decreasing.

therefore, the unregulated frequency of C is affecting the crystal and the time to
speed up then eventually slow down to
a halt.

Not unlike a sun becoming a quasar then a blackhole.

Honestly, Bob... Stop showing off...!

Well it is a bit more complicated than that. The simplest oscillator is
a cap and a coil in parallel. Give it a quick zap and it will oscillate
at a frequency determined by the values of capacitamce vs. inductance.
The oscillations will stop from loses without being refreshed by more
timed zaps.

Piezoelectric is like this (found in digital clocks), but it is like a
cyrstal rock between two metal plates. Smack it with a hammer (like in
those electric cigarette lighters), they will kick back with a voltage
(spark). Although kick it with a quick voltage spike and they vibrate.
And this vibating (oscillations) causes voltage oscillations as well.
And the lower the voltage, the weaker but faster oscillations they
produce. Thus cystal control clocks runs faster as the battery gets
weaker. Well until they get so weak that they can't cause it to vibrate
anymore.

The CMOS battery voltage should only come into play when the system is
disconnected from the mains.

interesting.

so the synopsis is: Just replace
the motherboard battery?

Correct. It takes approx. 3 minutes to find that out.
