system clock off by 1 hour after going to summer time

Binary package hint: gnome-system-tools

I have this problem on both Hardy (at home) and Maverick (at work).

To reproduce:
1) Install Ubuntu and Windows as they are "out of box"
2) Wait until the clock have to be adjusted (I think, you can reset the clock rather than travel in time)
3) See the clock automatically adjusted by Ubuntu
4) reboot to Windows

The clock will be off by 1 hour in the other direction.

What I expect: either adjust the clock manually or see it adjusted automatically
What I get: after I verify that the clock is properly automatically adjusted, the clock gets adjusted once more, at a date when it is not expected to change.

What can be done is a different question. A trivial solution would be to ask the user "sir, may I reset your clock?" or at least tell the user that the clock has been adjusted and as if it's ok (with an option to unde the adjustment).
A better solution would be to detect that other operating systems tried to reset the clock too.
