My project is in .net framwork 2.0 and i want to use TimezoneInfo class.

When i use the below line..it is giving an error like " Type TimezoneInfo is not defined"

Dim zones As ReadOnlyCollection(Of TimeZoneInfo) = TimeZoneInfo.GetSystemTimeZones()

Actually my requirement is to get all the timezones and functions for getting time by timezoneId.

How can i use the TimezoneInfo class in .Net 2.0 Application

Thank you,
Dilip.
