time reverts -1 hour across multiple systems, bios battery changed!

[tweaker563]

Hello,
i have this bug over a year, time reverts -1 hour.
I had it on windows 10 and i have it currently on fresh Windows 7 64 Ultimate.
I tried in past various solutions which google found with no luck.
I just changed battery in bios no effect !!!
Coudn't it cause some program.
I have only few programs currently installed: free alarm clock, free countdown timer, vlc, chrome, steam, battle.net, spotify, flux.
I am really confused how is this possible, it is annoying as hell.
Or if i had some program, which would show time in foreground of windows time, like osd, or overlay, i didn't find program like that.
This is torture, please help.

What time server are you connected to? By default time is synced with the server if you have wrong one set it will be wrong

 

[lehnerus2000]

Are you dual booting a Linux Distro?

What time server are you connected to? By default time is synced with the server if you have wrong one set it will be wrong

I have default time server: "time.windows.com".
I recall tried to change time server and i didn't help either.

Are you dual booting a Linux Distro?

No i have currently installed just Windows 7 Ultimate 64 bit.

Did you tried to manually change the time to be correct (i.e. not synchronize the time with server or something)? And if you did, does it stay correct?

Just to be clear, you currently have only Windows 10 and Windows 7 installed?

Though unlikely to be from the programs you use, I will still recommend you to remove all clock related programs while we are trying to fix the time.

 

[tweaker563]

I have currently only Windows 7 installed alone.
I think i tried that too, i will try that now and will see if it stays same.

Probably a silly question, but have you got your location set correctly. You say it is consistently 1 hour out, which is a normal time zone change, so that might explain your problem.

 

[Layback Bear]

After checking your time zone and the proper time in bios and Windows 7 I would remove free alarm clock, free countdown timer.
Then check if you have the same problem.

What is your location and what time zone do you have selected?

My location Prague and i had set utc +1 so that's fine.
I checked bios and time was correct.
Uninstalled both free alarm clock, free countdown timer.
Now nothing else than wait and see...

 

[tweaker563]

Again time reverted -1 hour...........

 

[Ranger4]

Have you actually got your time zone set for Prague & that means setting it from Time & Date & going into Change Time Zone & selecting the zone that includes Prague, or have you just manually advanced the clock by 1 hour.

 

[tweaker563]

I selected time zone for prague
Hm someone mentioned here dualboot with linux, it sometimes boot live usb, that may actually be it, because i noticed it right after using live usb.
Still not sure, will see.

Hi Tweaker,

got a way out there thought

Are you running behind a VPN that uses a different time zone.

Linux from live usb will definetly alter your win7 clock in taskbar (see below explanation). You'll either have to change windows time or your linux time so they match. Your Linux Live needs to have persistence to make the change to that and installed on DVD-RW BR-BE or USB media.

Operating systems store and retrieve the time in the hardware clock located on your motherboard so that it can keep track of the time even when the system does not have power. Most operating systems (Linux/Unix/Mac) store the time on the hardware clock as UTC by default, though some systems (notably Microsoft Windows) store the time on the hardware clock as the 'local' time. This causes problems in a dual boot system or booting from live cd/dvd/br if both systems view the hardware clock differently.
The advantage of having the hardware clock as UTC is that you don't need to change the hardware clock when moving between time zones or when Daylight Savings Time (DST) begins or ends as UTC does not have DST or timezone offsets.
Changing Linux to use local time is easier and more reliable than changing Windows to use UTC, so dual-boot Linux/Windows systems tend to use local time.

My dual boot Linux Lite/Win7 and Linux Lite/Win10 both behaved that way until i changed the clock settings on Linux,

Agreed.

 

[tweaker563]

Ye i downloaded program which synchronize clock after startup, hopefully it helps, i don't want persistent usb.

I have personally had Linux give me the same time problem a while back.
After going to their forum and completing their fixes I still had the same time problem.

Solved the problem by not using Linux. That has been some time ago. Maybe they have solved the problem by now.

It depends on the Linux Distro.
In general, if you want to dual boot Linux & Windows you will need to edit a Linux config file and/or a Windows Registry key.

Obviously a Live Linux CD/DVD can't be edited once it has been burned (although you could build a modified OS and then burn it to disc).

You can create a Live Linux USB that can be edited (or simply install the OS to a USB).


This wouldn't be an issue if Windows "Time Synched" on login (instead of at random).
