VB.NET Core Classes in a Nutshell

Name

TimeZone

Synopsis

This MustInherit class encapsulates a time zone. You cannot create a TimeZone instance directly because different time zones require different implementations of methods that involve time offsets due to daylight savings time. The most useful member of the TimeZone class is the shared CurrentTimeZone property, which provides a TimeZone object based on the localization settings of the current system.
