system time is incorrect

[x64user]

i'm actually posting here because somehow i couldn't start a new topic in the x64 section. i'm actually running windows xp x64 on my laptop which is a emachines m6805. the problem i'm having is that the system time is slowly losing time, as in the bottom right corner where the date and time is. I'd leave the computer and several hours later i'd come back and the time is off by say 5 minutes. For instance the time should read 7:00 but it reads 6:55 or something. I then go and syncronize the time with the online windows time but that's only a temporary fix; a few hours later it will be wrong again. Also, i have windows xp home dual booted on this machine and the time on that has never been wrong. does anyone know how i can fix this?

The clock speed on the client computer functions correctly when you synchronize the clock of the client computer with the clock of the server.

When W32Time determines the local clock offset, it makes the following adjustments to the time: • If the local clock time on the client computer is behind the current time on the server, W32Time changes the local clock time immediately.

• If the local clock time on the client computer is more than three minutes ahead of the current time on the server, W32Time changes the local clock time immediately.

• If the local clock time on the client computer is less than three minutes ahead of the current time on the server, W32Time quarters or halves the clock frequency on the client computer until the server clock and the client clock are synchronized.

Note If the local clock time on the client computer is less than 15 seconds ahead of the current time on the server, W32Time halves the clock frequency on the client computer. If the local clock time on the client computer is more than 15 seconds and less than 3 minutes ahead of the current time on the server, W32Time quarters the frequency.

The length of time that the clock runs at an unusual frequency depends on the size of the local clock offset that W32Time is correcting.

I'd bet that Windows time keeps slowing your clock, but as to why I would not know. You may want to look at the following KB article to see if any of these registry changes may help:

man i just looked at the time and it's now gotten 50 minutes behind the actual time. This is only a couple hours after i last changed the time back to normal. Still looking for a solution. Please help.

Have you read the KB I posted and at least tried some of the options there?

[x64user]

^I have read but not tried anything yet. I'm not sure exactly what it's telling me to do. All I know is I have to edit some registry files. Also it says it only pertains to Microsoft Windows 2000 Server, Microsoft Windows 2000 Advanced Server and Microsoft Windows 2000 Professional Edition.

It applies to all windows machines with the w32time service (which is 2000, XP, and 2003). It does seem like the w32time service is slowing your clock. What happens if you set the time correctly, then disable the w32time service? Also, is the time in your BIOS correct?

[x64user]

^ after i set the time and disable the w32time service, it still has the problem. what i'm thinking is that it is a compatability issue with the bios. also the time in the bios is correct, it is only when i go into windows xp x64 that the time becomes incorrect.

Well, anything is possible . And if w32time is disabled, we can rule that out. Have you contacted the vendor of the machine to see if there are any x64 issues on that hardware, or if a BIOS update is available?

i'm just wondering, is it just xp64?

do you have xp32 installed?

also, if you turn your bios on, go into the screen ware it shows the clock, and leave that for a few hours, see if the time is out..(just to make sure it is just a xp64 problem?)

[x64user]

yes i do have xp32-bit installed. the time is always correct on that sytem. it is only an x64 problem. the bios time is correct. i have now noticed that in xp x64 that after i get up in the morning, after the computer has been idle for the night, the time has now gotten off by many hours.

[cluberti]

That just does not compute. Why would it only happen to x64? This is weird...

Have you reinstalled, no software, no additional drivers than what the OS installs inbox, and see if the problem occurs in x64 at that point? I know it's drastic, but this just doesn't make sense.

[x64user]

yes i have reinstalled. i had installed x64 a several months back and had since uninstalled it. this time when i installed it again, i totally forgot it had this clock problem. and yes it did have the clock problem the last time. what i am thinking is that there is an incompatability with the windows x64 and the bios on my laptop. there is no newer bios from the manufacturer at the moment

[cluberti]

I suppose it's possible that there's an incompatibility - just seems really, really odd.

[Stead]

well i had a geeky look on the internet about that model, and all i found was updating your bios is a bad idea for some reason, unless you have the newer models? but they have the same model number, and the time issue is a known problem, but i couldn't seem to find any more information, sorry, just thought you'd appricate knowing other people have the same problem!
