[RESOLVED] How to get a TimeZone, its UTC offset in TimeSpan format?

Hi, Consider you have a clock control which works on GMT and has a UTC offset parameter in shh:mm:ss (System.TimeSpan) format. You also have a Combobox1 which contains all possible timezones via

Code:

---

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
ComboBox1.Items.AddRange(TimeZoneInfo.GetSystemTimeZones.ToArray)
End Sub

---

The goal is when you change the ComboBox1 index/item clock automatically converts the time.

Please note that Combobox may return something like "(UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna" but we only require its +01:00:00 (TimSpan).
(I am ParseExact and FormatProvider noob, sorry)
Sincerely,

Why not just use the Offset itself?

Why parse the crap out of a String?

Not sure how to do it. Can you hint a clue as a code example? I found learn.microsoft articles confusing... :'(

Maybe the last solution?

It's just a property. You get it like any other property. It's already a TimeSpan.

This is an obvious format mismatch/incompatibility. Can you say your point in another words?

Code:

Clock1.UtcOffset = DirectCast(ComboBox1.SelectedItem, TimeZoneInfo).BaseUtcOffset

Fantastic, it worked properly\!

You loaded TimeZoneInfos into your ComboBox, but the Items are always retrieved as Type Object. You need to cast as TimeZoneInfo so you can access the utc offset property… That’s why it worked…
