How can I detect timezone and whether daylight saving is applied on a client
PC/server using VB.NET?

Thanks

Hey Bill,

Check out the System.Timezone class. If that doesn't have what you
need, a chap called Michael Brumm has extended it to add some
functionality - http://www.michaelbrumm.com/simpletimezone.html

Dim t As TimeZone = System.TimeZone.CurrentTimeZone
Dim dls as boolean = t.IsDaylightSavingTime(Now)

Thanks Michel and Rad.

tz.getUtcOffset.totalHours works great!

One quick question: Do I really need to worry about saving time at all or
..getUtcOffset will detect it automatically?

Thanks again

Bill

Your pc clock will auto update daylightsaving if needed. So IMO it will
detect it automatically. Do keep in mind, that if you have multiple
apps running on different pc's, time settings could be different.
