My comments were not about the patch (which I admit I don't really
understand, as I don't use icalendar), but about the attempts to see
what happens with time under different TZ settings.

As for the patch, I've looked at it again now, and I don't think it's
specific to MS-Windows, is it?  If so, and if you think it's good,
feel free to install.

Thanks.
