Clock hour changes when previously booted with Windows

[F_style]

WTH!?

On Windows 7 the hour is correctly displayed, but when booting back with openSUSE 12.2 x86_64 GNOME 3.4 it goes back 5 hours, and I have to change it again!
What's this?

Have a look at this blog as it might pertain to the problem that you see.

What is UTC or GMT Time & a possible issue with openSUSE 12.2 and its solution. - Blogs - openSUSE Forums

Thank You,

Most operating systems correctly set the hardware clock to UTC/GMT,
which is the time that computers all use internally; these OS's (Linux
included) then calculate the timezone and daylight savings time offset
and display that to you when required. windows incorrectly sets the
hardware clock to local time. As a result when you boot back into Linux
your time is off by your current different from GMT (5 hours could be
CDT (central time in the USA) during daylight savings time, or eastern
time during non-daylight-savings-time, or somewhere else over in Asia if
it's +5 instead of -5.

Easiest fix: stop using windows or other dumb OS's.

Other easy fix from the OS that accommodates ****, even windows ****, go
into Yast in your time settings and have Linux treat your hardware clock
as if set to local time.

Good luck.

Must be one of the most frequently asked questions these days. You did not search the forum
before asking, did you? :-)

That is all correct, but you missed that there is a bug in 12.2 where this setting is not saved.
See @jmcdaniel3's blog and the other (several) threads abbout this since 12.2 was released.

I have not looked, but I wonder if this is in the release notes? Mmm, yes, it is. So, it is the
OP fault for not reading :-) Or perhaps not. The info in the release notes is too brief and
incomplete.

It's not difficult to alter the registry in Windows so that it uses UTC. Simply paste the following into a notepad file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]
"RealTimeIsUniversal"=dword:00000001

and save it with the .reg extension. Then double click on it and agree with everything you are asked. The key will be added to the registry database and you can set openSUSE to use UTC too. Then you should not have any further problems.

I don't think Windows is dumb just because a small amount of effort is required to change its default behaviour.

I have changed this and then my widnows as well as linux clocks were off I guess changing the clock in the BIOS is required for this as well.
