C# - How to get Time Zone in asp .net application?
TimeZone.CurrentTimeZone Property to Select TimeZone in Dropdown
A time zone is a geographical region in which the same time is used. The TimeZone class recognizes only the local time zone, and can convert times between Coordinated Universal Time (UTC) and local time.
- Retrieving a time zone that is already defined by the operating system.
- Enumerating the time zones that are available on a system.
- Converting times between different time zones.
- Creating a new time zone that is not already defined by the operating system.
- Serializing a time zone for later retrieval.
For example find the source code below :
Default.aspx
<%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="_Default"
%>
