We could build a database of known Microsoft timezones and map them to
ISO timezones. It has to be done just once and then updated very
rarely--timezone names don't change often. The full list of timezones
is in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Time Zones
according to the article, so it may be possible to build the full list
of keys on a single machine and then fill it in with the mappings.
