a écrit : Changes in the ``datetime``-module --------------------------------------
A new ``is_dst`` parameter is added to several of the `tzinfo` methods to handle time ambiguity during DST changeovers.
* ``tzinfo.utcoffset(self, dt, is_dst=True)``
* ``tzinfo.dst(self, dt, is_dst=True)``
* ``tzinfo.tzname(self, dt, is_dst=True)``
The ``is_dst`` parameter can be ``True`` (default), ``False``, or ``None``.
``True`` will specify that the given datetime should be interpreted as happening during daylight savings time, ie that the time specified is before the change from DST.
Why is it True by default? Do we have statistics showing that Python gets more use in summer?
My question exactly. The rest sounds good -- definitely use the system tz database on Unixy systems, pre-install on Windows and make updating easy. Some bikeshedding about static I don't really understand, so I'll leave to others. -- --Guido van Rossum (python.org/~guido)
