I had to convert times from Windows to iOS on a prior project. We finally
settled on an around-the-world solution which geolocated our target
location, called a web service (geonames.org) to retrieve the TZ database
name for that location, and then built the NSTimeZone structure calling
[NSTimeZone timeZoneWithName:] using the TZ database name.
Most operating systems use the TZ database for managing time zones. The TZ
database has a single, unambiguous name for each locale in the fashion
"america/chicago". Windows uses their own format which requires you to know
if the locale is observing daylight savings time (i.e. "central standard
time" vs "central daylight time"). This is a real problem .. a problem that
TZ database solves for you. Too bad Microsoft didn't see it that way.
