ManagementDateTimeConverter in C# .Net windows application

[DKn]

Hello All,

I am having an C#.Net windows application.There I am using WMI class Win32_OperatingSystem to get the information of operating system. In this class we are having a Parameter Called "LocalDateTime".
If the time zone is "(GMT+5:30) chennai,kolkata,Mumbai,Newdelhi" we will get localdatetime from WMI as "20070327182923.82800+330" . This value I have converted to datetime by using ManagementDateTimeConverter
DateTime Dt;
Dt = ManagementDateTimeConverter.ToDateTime
string strFormatedDate = Dt.ToString("MMM/dd/yyyy hh:mm:ss tt");
("20070327182923.82800+330"); This is working fine and giving the result like Mar/27/2008 06:29:23

the problem comes If I change the Time zone, Then i tried get the localdatetime dynamically , WMI is returning the correct value , but the ManagementDateTimeConverter is not giving the correct value.It is giving the previous time zone value only.

But when i close the appliaction and run it again then it is giving current timezone time what ever we have selected.

What is the problem here? can anyone give any solution to get current time zone time.

Thanks in advance...

Why not just use DateTime.Parse() ?

DateTime dt = DateTime.Parse("20070327182923.82800+330" );

Should give you a datetime object of the correct value.



Also, there seems to be some CLR caching involved with timezone information.
You can do something like the following to reset what the cached timezone is.

try
{//System.Reflection.
   FieldInfo fi = typeof(TimeZone).GetField("currentTimeZone", BindingFlags.NonPublic | BindingFlags.Static | BindingFlags.Instance);
   fi.SetValue(null, null);
}
catch (Exception ee)
{
}
