It is incorrectly adjusting for daylight bias in 10.7.0 on Windows. This will be set back to previous 10.6.2 behavior in a future version.
The intend was to make values compatible between Unix and Windows during daylight savings time. But it breaks when outside of daylight savings time. The assumption was, that the daylight bias is only reported when daylight savings is active, which is not true at least on Windows. Unfortunately the whole daylight savings behavior is inconsistent even between different Unix flavors.
