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.

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,

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).
