Get the Olson TZ name for the local timezone?

Question

How do I get the Olson timezone name (such as Australia/Sydney) corresponding to the value given by C\'s localtime call?

This is the value overridden vi

Answer 1

The tzlocal module for Python is aimed at exactly this problem. It produces consistent results under both Linux and Windows, properly converting from Windows time zone ids to Olson using the CLDR mappings.
