Daylight saving time and other time zone related information
Sometimes you need to know just that little bit more about the time zone a user is in. You might need to know the time difference between their local time and UTC, whether they are in daylight saving time or when the daylight saving period starts and ends.
Well the TimeZone type is our friend. The TimeZone.CurrentTimeZone will give you all sorts of information like if daylight saving time is in effect, the IsDaylightSavingTime() function, or offset from UTC, the GetUtcOffset() function.
Additionally the GetDaylightChanges() functin will give you more detail about when the daylight saving period starts and ends and the time change involved.
Enjoy!
