By default, it caches a single instance of the ZoneInfoFile object and returns that. :param new_instance: If ``True``, a new instance of :class:`ZoneInfoFile` is instantiated and used as the cached instance for the next call.

This is *not* equivalent to ``dateutil.tz.gettz()``, which selects an appropriate time zone based on the inputs, favoring system zoneinfo. This is ONLY for accessing the dateutil-specific zoneinfo (which may be out of date compared to the system zoneinfo). .. deprecated:: 2.6 If you need to use a specific zoneinfofile over the system zoneinfo, instantiate a :class:`dateutil.zoneinfo.ZoneInfoFile` object and call :func:`dateutil.zoneinfo.ZoneInfoFile.get(name)` instead. Use :func:`get_zonefile_instance` to retrieve an instance of the dateutil-provided zoneinfo. zzoneinfo.gettz() will be removed in future versions, to use the dateutil-provided zoneinfo files, instantiate a ZoneInfoFile object and use ZoneInfoFile.zones.get() instead.
