New submission from Alexander Belopolsky <belopol...@users.sourceforge.net>:
See python-dev post for motivation. http://mail.python.org/pipermail/python-dev/2010-August/102842.html I am attaching a patch implementing the proposed method in datetime.py. I will also paste the code below. Note that this is only prototype. Real implementation will use tm_zone and tm_gmtoff components of tm structure on platforms that supply them. @classmethod def localtime(cls, t=None, isdst=-1): """Return local time as an aware datetime object. If called without arguments, return current time. Otherwise *t* is converted to local time zone according to the system time zone database. If *t* is naive (i.e. t.tzinfo is None), it is assumed to be in local time. In this case, a positive or zero value for *isdst* causes localtime to presume initially that summer time (for example, Daylight Saving Time) is or is not (respectively) in effect for the specified time. A negative value for *isdst* causes the localtime() function to attempt to divine whether summer time is in effect for the specified time. """ if t is None: t = _time.time() else: if t.tzinfo is None: tm = t.timetuple()[:-1] + (isdst,) t = _time.mktime(tm) else: delta = t - datetime(1970, 1, 1, tzinfo=timezone.utc) t = delta.total_seconds() tm = _time.localtime(t) if _time.daylight: if tm.tm_isdst: offset = _time.altzone tzname = _time.tzname[1] else: offset = _time.timezone tzname = _time.tzname[0] tz = timezone(timedelta(seconds=-offset), tzname) return cls.fromtimestamp(t, tz) ---------- assignee: belopolsky components: Extension Modules, Library (Lib) files: datetime-localtime-proto.diff keywords: patch messages: 113067 nosy: belopolsky priority: normal severity: normal status: open title: Add aware local time support to datetime module type: feature request versions: Python 3.2 Added file: http://bugs.python.org/file18410/datetime-localtime-proto.diff _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue9527> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
