title: How do you return the system time zone as a string?
body: <p>I have an app where I set time zones for various cities around the globe.  I have no problem doing this and it works great.  When the app first loads, it finds your current location (lat &amp; long) and sets the time zone using the device default time zone.  I need to return the default time zone in a string, so I can display it.  I don't want "GMT" or "EDT", I would like it in the format of "America/New_York" or 'Europe/London".  Any ideas?</p>
