Time is nontrivial, but thankfully its support is first-class in Python. ``dateutils`` provides some additional tools for working with time. Additionally, timeutils provides a few basic utilities for working with timezones in Python. The Python :mod:`datetime` module's documentation describes how to create a :class:`~datetime.datetime`-compatible :class:`~datetime.tzinfo` subtype. It even provides a few examples. The following module defines usable forms of the timezones in those docs, as well as a couple other useful ones, :data:`UTC` (aka GMT) and :data:`LocalTZ` (representing the local timezone as configured in the operating system). For timezones beyond these, as well as a higher degree of accuracy in corner cases, check out `pytz`_ and `dateutil`_. .. _pytz: https://pypi.python.org/pypi/pytz .. _dateutil: https://dateutil.readthedocs.io/en/stable/index.html N)tzinfo timedeltadatedatetimecld}|j|jdzz}|j||zz}||z S)aaFor those with older versions of Python, a pure-Python implementation of Python 2.7's :meth:`~datetime.timedelta.total_seconds`.

When *inclusive* is True, the final date may be *stop*, **if** *step* falls evenly on it. By default, *step* is one day. See details below for many more details. Args: start (datetime.date): The starting date The first value in the sequence. stop (datetime.date): The stopping date. By default not included in return. Can be `None` to yield an infinite sequence. step (int): The value to increment *start* by to reach *stop*. Can be an :class:`int` number of days, a :class:`datetime.timedelta`, or a :class:`tuple` of integers, `(year, month, day)`. Positive and negative *step* values are supported. inclusive (bool): Whether or not the *stop* date can be returned. *stop* is only returned when a *step* falls evenly on it. >>> christmas = date(year=2015, month=12, day=25) >>> boxing_day = date(year=2015, month=12, day=26) >>> new_year = date(year=2016, month=1, day=1) >>> for day in daterange(christmas, new_year): ... print(repr(day)) datetime.date(2015, 12, 25) datetime.date(2015, 12, 26) datetime.date(2015, 12, 27) datetime.date(2015, 12, 28) datetime.date(2015, 12, 29) datetime.date(2015, 12, 30) datetime.date(2015, 12, 31) >>> for day in daterange(christmas, boxing_day): ... print(repr(day)) datetime.date(2015, 12, 25) >>> for day in daterange(date(2017, 5, 1), date(2017, 8, 1), ... step=(0, 1, 0), inclusive=True): ... print(repr(day)) datetime.date(2017, 5, 1) datetime.date(2017, 6, 1) datetime.date(2017, 7, 1) datetime.date(2017, 8, 1) *Be careful when using stop=None, as this will yield an infinite sequence of dates.* z%start expected datetime.date instancez,stop expected datetime.date instance or Nonerr&zBstep expected int, timedelta, or tuple (year, month, day), not: %r Ncy)NFr3)nowstops rzdaterange..srr)r-r,) isinstancer TypeErrorrrr9operatorgtgeltledivmodr,replacer-) startrgstep inclusivey_stepm_stepd_stepfinishedrfm_y_step cur_months r dateranger{8spf eT "?@@ JtT*FGG2!%Vc&k&#F , FI & 8:>?@ @ frkF |* $"+8;;"+8;; CsD!
