Supported operators:
- add, subtract timedelta
- unary plus, minus, abs
- compare to timedelta
- multiply, divide by int/long
In addition, datetime supports subtraction of two datetime objects
returning a timedelta, and addition or subtraction of a datetime
and a timedelta giving a datetime.

d.timetuple() is equivalent to

date(d.year, 1, 1).toordinal() + 1, -1)

isoweekday‘ s c C s d S( se Return a 3-tuple, (ISO year, ISO week number, ISO weekday).
The ISO calendar is a widely used variant of the Gregorian calendar.
See http://www.phys.uu.nl/~vgent/calendar/isocalendar.htm for a good
explanation.
The ISO year consists of 52 or 53 full weeks, and where a week starts
on a Monday and ends on a Sunday. The first week of an ISO year is the
first (Gregorian) calendar week of a year containing a Thursday. This
is called week number 1, and the ISO year of that Thursday is the same
as its Gregorian year.
For example, 2004 begins on a Thursday, so the first week of ISO year
2004 begins on Monday, 29 Dec 2003 and ends on Sunday, 4 Jan 2004, so
that date(2003, 12, 29).isocalendar() == (2004, 1, 1) and
date(2004, 1, 4).isocalendar() == (2004, 1, 7).
N( ( ( ( sE /usr/lib64/python2.6/site-packages/zope/interface/common/idatetime.pyt isocalendarš s c C s d S( s¥ Return a string representing the date in ISO 8601 format.
This is 'YYYY-MM-DD'.
For example, date(2002, 12, 4).isoformat() == '2002-12-04'.
N( ( ( ( sE /usr/lib64/python2.6/site-packages/zope/interface/common/idatetime.pyt isoformat s c C s d S( s4 For a date d, str(d) is equivalent to d.isoformat().N( ( ( ( sE /usr/lib64/python2.6/site-packages/zope/interface/common/idatetime.pyt __str__´ s c C s d S( sp Return a string representing the date.
For example date(2002, 12, 4).ctime() == 'Wed Dec 4 00:00:00 2002'.
d.ctime() is equivalent to time.ctime(time.mktime(d.timetuple()))
on platforms where the native C ctime() function
(which time.ctime() invokes, but which date.ctime() does not invoke)
conforms to the C standard.

N( ( ( ( sE /usr/lib64/python2.6/site-packages/zope/interface/common/idatetime.pyR Ó s c C s d S( sk Return the current local date and time.
If optional argument tz is None or not specified, this is like today(),
but, if possible, supplies more precision than can be gotten from going
through a time.time() timestamp (for example, this may be possible on
platforms supplying the C gettimeofday() function).
Else tz must be an instance of a class tzinfo subclass, and the current
date and time are converted to tz's time zone. In this case the result
is equivalent to tz.fromutc(datetime.utcnow().replace(tzinfo=tz)).
See also today(), utcnow().
N( ( t tz( ( sE /usr/lib64/python2.6/site-packages/zope/interface/common/idatetime.pyt nowÚ s c C s d S( sÆ Return the current UTC date and time, with tzinfo None.
This is like now(), but returns the current UTC date and time, as a
naive datetime object.
See also now().
N( ( ( ( sE /usr/lib64/python2.6/site-packages/zope/interface/common/idatetime.pyt utcnowé s c C s d S( sK Return the local date and time corresponding to the POSIX timestamp.
Same as is returned by time.time(). If optional argument tz is None or
not specified, the timestamp is converted to the platform's local date
and time, and the returned datetime object is naive.
Else tz must be an instance of a class tzinfo subclass, and the
timestamp is converted to tz's time zone. In this case the result is
equivalent to
tz.fromutc(datetime.utcfromtimestamp(timestamp).replace(tzinfo=tz)).
fromtimestamp() may raise ValueError, if the timestamp is out of the
range of values supported by the platform C localtime() or gmtime()
functions. It's common for this to be restricted to years in 1970
through 2038. Note that on non-POSIX systems that include leap seconds
in their notion of a timestamp, leap seconds are ignored by
fromtimestamp(), and then it's possible to have two timestamps
differing by a second that yield identical datetime objects.
See also utcfromtimestamp().

an aware datetime with no conversion of date and time members.

date and time members so the result is the same UTC time as self, but
in tz's local time.
tz must be an instance of a tzinfo subclass, and its utcoffset() and
dst() methods must not return None. self must be aware (self.tzinfo
must not be None, and self.utcoffset() must not return None).
If self.tzinfo is tz, self.astimezone(tz) is equal to self: no
adjustment of date or time members is performed. Else the result is
local time in time zone tz, representing the same UTC time as self:
after astz = dt.astimezone(tz), astz - astz.utcoffset()
will usually have the same date and time members as dt - dt.utcoffset().
The discussion of class tzinfo explains the cases at Daylight Saving
Time transition boundaries where this cannot be achieved (an issue only
if tz models both standard and daylight time).
If you merely want to attach a time zone object tz to a datetime dt
without adjustment of date and time members, use dt.replace(tzinfo=tz).
If you merely want to remove the time zone object from an aware
datetime dt without conversion of date and time members, use
dt.replace(tzinfo=None).
Note that the default tzinfo.fromutc() method can be overridden in a
tzinfo subclass to effect the result returned by astimezone().
