[ANN] python-dateutil 0.1

[Gustavo Niemeyer]

What is it?
-----------
The dateutil module provides powerful extensions to the standard
datetime module, available in Python 2.3+.

Features
--------

* Computing of relative deltas (next month, next year,
next monday, last week of month, and a lot more);

* Computing of relative deltas between two given
date and/or datetime objects;

* Computing of dates based on very flexible recurrence rules
(every month, every week on Thursday and Friday, every
Friday 13th, and a *LOT* more), using a superset of the
iCalendar RFC specification. Parsing of RFC strings is
supported as well.

* Generic parsing of dates in almost any string format;

* Timezone (tzinfo) implementations for tzfile(5) format
files (/etc/localtime, /usr/share/zoneinfo, etc), TZ
environment string (in all known formats), iCalendar
format files, given ranges (with help from relative deltas),
local machine timezone, fixed offset timezone, and UTC
timezone.

* Computing of Easter Sunday dates for any given year,
using Western, Orthodox or Julian algorithms;

* More than 400 test cases.


Where to get it?

It will be hard to find something you can't do.

How may work days until the end of the month?
dtstart=now,until=now.replace(day=31))))

Hummm.. interesting enough, this result is not right. Today should
also be counted in this case. There's a small bug related to
micrseconds handling in the module: since the recurrence is compared
against a date without microseconds, the recurrence is not greater
than the dtstart passed. I haven't got this because all 415 testcases
were using datetime instances without microseconds. Well, we
have 417 now.. ;-)

Here is the right result, with the fix:
dtstart=now,until=now.replace(day=31))))

Thanks!

wow great. Do we have a to find the next bank holiday microsecond .

With this functionality it'll make calculating those bond prices even
more interesting.

Oh.. Sorry. I'll include it. It's released under the Python
Software Foundation license, the same as Python itself.
