[Python-Dev] PEP 431 Updates

[Antoine Pitrou]

Hi,

Le Mon, 28 Jan 2013 11:01:05 +0100,
Lennart Regebro <regebro at gmail.com> a écrit :
> This function takes a name string that must be a string specifying a
> valid zoneinfo time zone, i.e. "US/Eastern", "Europe/Warsaw" or
> "Etc/GMT".

Will non-ambiguous shorthands such as "Warsaw" and "GMT" be accepted?

> The ``is_dst`` parameter can be ``False`` (default), ``True``, or
> ``None``.
> 
> ``False`` will specify that the given datetime should be interpreted
> as not happening during daylight savings time, i.e. that the time
> specified is after the change from DST.
> 
> ``True`` will specify that the given datetime should be interpreted
> as happening during daylight savings time, i.e. that the time
> specified is before the change from DST.
> 
> ``None`` will raise an ``AmbiguousTimeError`` exception if the time
> specified was during a DST change over. It will also raise a
> ``NonExistentTimeError`` if a time is specified during the "missing
> time" in a change to DST.

NonExistentTimeError can also be raised for is_dst=True and
is_dst=False, no? Or am I misunderstanding the semantics?

Regards

Antoine.
