In a nutshell - not well.

Windows has a set of keys in the registry that store the timezone 
information. After Windows 95 they gave up on following the timezone in 
Israel. I guess we can try and figure out the registry timezone info 
structure, but then we'll be only as good as Windows, while we actually 
have enough information to be better! That sounds like an awful shame.
