TimeZoneInfo vs. Olson database

Question

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.

See also [the timezone tag wiki](http://stackoverflow.com/tags/timezone/info). — Matt Johnson-Pint, Feb 04 '15 at 01:33

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.
