Matching clock time when booting from different OSes

If you're like me and have more than one OS installed which boot now and then, may be you have noticed that the clock doesn't match between them. The cause of this is that Windows uses Local Time instead of UTC.

You can enable UTC time mode editing the registry at key:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\TimeZoneInformation]

and add a DWORD with a value of 1.

Beware that have been reports of malfunction of the clock. I personally haven't noticed any problems though.
