I have my hardware clock set up in UTC. Windows 7 lets me add extra clocks to be shown when I click on the task bar clock, but the always-visible task bar clock itself remains in UTC. Can I change this without altering the hardware clock time zone?

I am interested not only in using UTC hardware clock, but using any time zone hardware clock while displaying different time zone clock in the taskbar. For example, a colleague of mine working intensively with Russian partners has hardware clock configured in CET (as everybody in the European office) but relies on MSK time in practice.

I think I wouldn't mind using a third party accessory (perhaps even reasonably paid one) but would like it to keep the original Windows 7 clock look-and-feel intact.

I think setting the registry entry from this article will allow your time to display properly. Per the article, create a registry file in Notepad with the following in it:

Windows Registry Editor Version 5.00

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

Open the .reg file you just created, answer yes, and restart your computer.

To set the time back to the default, non-UTC time calculation method, you can make a .reg file with the following and run it:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation] “RealTimeIsUniversal”=dword:00000000

Officially there's no way to do this. You could try registry hacks but I found that it can be very buggy. Restarting your computer or resyncing the clock online causes quirks and your clock might end up being way off and more of a bother than actually just using local time.
