TimeZone Not Found Exception [duplicate]

Question

I want to convert Indian DateTime object to Eastern DateTime object. Means I want to change time zone of particular DateTime object. For this I have written following code:

string easternZoneId = "Eastern Standard Time";
TimeZoneInfo easternZone = TimeZoneInfo.FindSystemTimeZoneById(easternZoneId);

string indianZoneId = "India Standard Time";
TimeZoneInfo indianZone = TimeZoneInfo.FindSystemTimeZoneById (indianZoneId);

DateTime d = TimeZoneInfo.ConvertTime (DateTime.Today, indianZone, easternZone);

When I try to run this statement I am getting, following exception in Console.

How to run this code? I want to convert my time into eastern time.

EDIT: Right now I am running my code in Unity Editor. I have iMac system. I want to run this code for iPhone devices.

Answer 1

"India Standard Time" does not exist on my PC. You can list all the supported timezones on your PC (I have noticed that this can be different on other PC's) by listing them like this:

var timeZones = TimeZoneInfo.GetSystemTimeZones(); 
foreach (TimeZoneInfo timeZone in timeZones)
{
    Console.WriteLine(timeZone.Id);
}

Out:

• Dateline Standard Time
• UTC-11
• Hawaiian Standard Time
• ...
