I don't often boot into MS Windows and deal with the change in clock when I get back into Linux afterwards. This should solve that :) -- Joost

See http://superuser.com/a/621218 That being said, I haven't tried it myself, nor have I heard any direct reports of issues, but it is something to be aware of. - -wraeth -BEGIN PGP SIGNATURE- Version: GnuPG v2 Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iF4EAREIAAYFAlO8fUcACgkQXcRKerLZ91nj5AD5Ad3PgRNNEfuMuC44In7D+/b9 6MZ+AbykrHqKGkgaBYUA/1DsK594ulwKe5ZNQqLmgO6A2xFX6AbTglxAg1AV4ECT =667V -END PGP SIGNATURE-
