title: Standard Time Zone Names/IDs
body: <p>Are there standardized time zone names that are recognized by different operating systems and/or platforms?  For example, it doesn't look like the strings returned by <code>[NSTimeZone knownTimeZones]</code> in Objective C match the IDs returned by <code>TimeZoneInfo.GetSystemTimeZones()</code> in .NET.  Am I going to have to write conversion tables if I want to recognize time zones between systems?</p>
