Have you checked, whether your timezone setting is set correctly?

"if i try to update the time from the desktop by double clicking the time on the bottom right corner"

Right click on the clock, then click 'Adjust Date/Time'. If it resets after shutting down the system, your CMOS battery may be bad.

Two reasons I've seen this happen. One , you have incorrectly set the time zone(central America instead of Central Time(us&canada)). Two: Your time in the bios is incorrectly set. If you have set the bios time correctly, check its battery volts to see if it should be replaced.

the time zone is correct as it is supposed to be.
i don't think double clicking and right click -> adjust date & time clicking make any difference...
if i set the time in bios it stays well for a week or so, and then it starts deviating.
but the real problem is that after the time has drifted much and i try to change to the correct time, xp won't just take it. when i enter the new time and click apply, the next moment the time falls back to the drifted time.
i will surely check the cmos battery, but the reason that makes me think this is not an issue with the battery is that why xp doesn't allow to change the time?

someone please tell what should be the battery volt if it works correctly and what if not?

what i feel is that xp or something else is not just allowing the change of time. could this be caused by zone alarm firewall?

What is not always realised is that the CMOS battery is rechargeable to some extent. I used to recharge watch batteries but it was pointless because they only lasted about 6 months. What I'm saying is that when the system is turned off there is no charge at all, so it starts dying.

Tekbird, Cmos batteries run 3 volts or 3.2 volts tested. But if the battery was dying the date would change too. If your cmos battery is fully charged and your region is set properly. And even with synchronizing to microsoft server doesn't change the problem, then your leaving out a lot of info.
Let say you failed to mention your XP computer is on a domain, then it is synchronizing to the domain controllers time so kerberos will work properly. Other then that, you would have to break it down to some installed application that was causing the problem.

thanks all you geeks for ur suggestions. i wouldn't know if iam on a domain. but am certainly connected to Internet via an ADSL modem-router. i tried disabling the automatic configuration of time in the router's configuration page. also i tried shutting down the zone alarm firewall. either of these wouldn't make any difference. i will replace the battery and try.

but my question is, even if the battery is dead, while on power (switched on) I should be able to change the time via usual steps. unfortunately, this is not what happening. anyobody have a clue?

It is possible for batteries to actually be draining power if they are faulty but it's a most unusual occurence. I agree it's best to change the battery as they are cheap and its good to eliminate even the less likely.

It's very odd that you can't reset time in the usual way and on the face of it does look more like some obscure Windows issue.

I haven't.

This post might get revisited by others who have already input and there could be new participants. If anyone has a solution I'm sure they will willingly provide it.

Disconnect the computer from the network and set the clock manually.
See, whether you can set the time and it does not fall back to the old wrong time.
If this works, click Start / Run and type in services.msc.
Then disable the Windows Time Service.
After that, connect the computer to the network and see, whether the time can be set and will hold the correct time.

hi paulsep, thanks for reviewing my query!
I followed the steps mentioned.
unfortunately, they don't make any good
I clearly followed the instructions for no change in the time behavior.
now I remember last time the system had the same problem and it was resolved after reinstalling xp. but after some time (may be a few month) the problem is occurring now again. now i suspect this could be a problem with the xp itself.....

Before reinstalling windows xp, you can try to use w32tm.exe in a CMD windows.
For help, use w32tm.exe /?.
E.g.:
w32tm /dumpreg
shows the setting in the registry.

I guess, your problem is caused by a wrong time source setting in the registry.
Because you set the time correctly and after a short amount of time, the time switches back to the wrong time.

Have you checked, whether the difference in time is always the same,. when you set the time correctly and it switches back to the wrong.
Maybe it's always let's say 8 hours.

ok, following is the registry details of time that produced from the w32tm /dumpreg command:

i cannot remember the exact deviation in time, but currently it's some 45 minutes. one thing i remember is that this deviation never was in the order of hours.
now the computer is totally unplugged from network and the automatic update is using the windows default time server. another thing i have noticed is, when i click 'update now' for automatic updates it executes it successfully, but the time automatically falls back to the deviated time (of course only when it's connected :) ).

Ok, so we have to check some registry settings at your machine.
Open Notepad and copy and past the lines between [code] and [/code] into Notepad.
Save the file as e.g. modtime.reg to your desktop.
Doubleclick the modtime.reg file to import the registry changes. Then restart your computer.

[code]

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters]
"NtpServer"=",0x1"
"Type"="NoSync"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config]
"AnnounceFlags"=dword:0000000a

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer]
"Enabled"=dword:00000001

[/code]

ok, before doing that let me be clear on one thing. would this completely disable the automatic update? because automatic update seemed to be a good choice in any time deviation, if at all happening due to errors in the RTC module.

Yes it will disable the automatic time update.
Therefore, you may first open regedit, locate the registry entries and write down the current values.

Then you can copy the reg file, I posted in Response #17 and change the values with the current values.
So you have 2 reg files and can simply change back to the old state by doubleclicking the second file you created.
