VB.net output datetime with timezone and offset

I wish to construct a DateTime which looks like below in Visual Basics:

Wed Aug 23 2017 10:00:00 GMT+0530

Can anyone please suggest how to construct a DateTime info where timezone info could also be shown as above?

A DateTime has a Kind which is one of DateTimeKind.Local, DateTimeKind.Utc, or DateTimeKind.Unspecified, so although it has some time zone information, it is too limited to specify another offset.

A DateTimeOffset can hold other offsets, so it may suit your purposes better:

Module Module1

    Sub Main()
        Dim hereAndNow = DateTime.Now
        Dim utc = DateTime.UtcNow
        Dim noTzi = Date.SpecifyKind(utc, DateTimeKind.Unspecified)

        Dim inIndia As New DateTimeOffset(noTzi, TimeSpan.FromHours(5.5))

        Console.WriteLine(hereAndNow.ToString("yyyy-MM-dd HH:mm:ss K"))
        Console.WriteLine(utc.ToString("yyyy-MM-dd HH:mm:ss K"))
        Console.WriteLine(inIndia.ToString("yyyy-MM-dd HH:mm:ss 'GMT' K"))

        Console.ReadLine()

    End Sub

End Module

Outputs:

2017-08-23 11:36:55 +01:00
2017-08-23 10:36:55 Z
2017-08-23 10:36:55 GMT +05:30

I had to set the Kind of the DateTime variable utc to DateTimeKind.Unspecified to be able to use it in the DateTimeOffset constructor.

You should use the K custom format specifier for displaying time zone information.

You can do something like below...

Dim dt as DateTime = DateTime.UtcNow
Dim output as String = dt.ToLocalTime().ToString("MMM dd, yyyy HH:mm:ss tt ""GMT"" zzz")
Console.WriteLine(output) 'Outputs Aug 23, 2017 11:16:29 AM GMT +01:00

See Custom Date and Time Format Strings for more information.
