Do TimeZoneInfo and Olson database use identical identificators for time zones?
I get timezone id from GeoNames service (which is based on Olson database) and want to retrieve day light saving information for that timezone.

The unicode consortium keeps a mapping between Olson database and Windows TimeZone Ids, which can be accessed here.
Also see this SO question and answers for more daylight savings info (Daylight saving time - do and don’ts).
No they don't use the same identifiers. A possible solution is to use Noda-Time which foregoes TimeZoneInfo in favour of Olson timezones.
