windows xp Windows time not stable

[Guest Raneen Dirawi]

I have windows xp professional on my laptop and the time jumbs forward ~5

minutes for ~15 seconds and then backwards. It happens a lot; once every ~55

minutes.

I have no idea why this happens! I hope you have an answer for this problem...

My time zone is Jerusalem (GMT+02:00) and the "Automatically adjust clock

for daylight saving changes" option is checked.

[Guest Jonathan Boyko]

Ehlo Raneen,

Is this happening when you restart the computer, or just during work?

It must be noted that the "clock" in most PCs is not a "true" clock.

It is a chip that has been set up to simulate a clock. It can be

affected by several applications. Your best bet is to locate a

"better" network time sync application that will contact an Internet

time server and adjust your PC's clock more often than Microsoft's

applet.

Hi Jonathan,

 

It happens all the time during work!

If your computer is on a network, one designated server is usually the

timekeeper for all workstations.

 

The built in clock should try to sync with one of two servers that XP

knows about. You can see them in Start, Settings, Control Panel, Date

and Time, Internet Time tab.

 

One is time.nist.gov, the other is time.windows.com

 

Choose either one and click update now. To work, the W32tme service

must be running and your firewall must allow access to that service.

 

This is usually fine and syncs one a week or when you do it by hand,

or from other methods and things can be tweaked.

 

You should first test this process manually to be sure it works and

resolve any issues. The Application Event log will show any errors,

so if this doesn't work, expect the time to be wrong.

 

I like to use http://www.worldtimeserver.com/atomic-clock/

 

I have this for XP and two atomic wall clocks around me and they are

always in perfect sync with my XP clock.

If once a week is not good enough, adjust the server, sync settings,

etc. here:

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time

\TimeProviders\NtpClient

Is Special Poll Interval what needs to be changed?

I had several CurrentControlSets.

I only have one CurrentControlSet, and it is the SpecialPollInterval.

The default value of 604800 seconds equals 1 week.

 

I do have a couple ControlSets, but only one CurrentControlSet.

I would recommend getting an outside program to synchronize your

clock.

 

The clock in the computer is quite accurate.

 

I use to program in assembly and as it shows below, the chip can

provide some very accurate timings.

 

To fix the time zone problem, I had to change to the Eastern Time Zone

instead of using the Central Time Zone

which is where I live. ??

I prefer cesium to any silly onboard clocking mechanism.

 

A cesium based clock can maintain a time measurement accuracy of 2

nanoseconds per day or one second in 1,400,000 years. It is the most

accurate realization of a unit that mankind has yet achieved and that

is good enough for me.

How much do they run?
