parse a date/time string to a `datetime` instance (Python)

2010-04-02T07:32:17-07:00

Python recipe 577135 by Trent Mick (date, datetime, parse, time). Revision 2.

>>> import datetime
>>> str(datetime.datetime.now())
'2010-03-21 21:33:32.750246'
>>> str(datetime.date.today())

Flexible datetime parsing (Python)

2012-08-21T07:35:34-07:00

Python recipe 578245 by Glenn Hutchings (datetime, parsing).

The strptime() method of datetime accepts a format string that you have to specify in advance. What if you want to be more flexible in the kinds of date your program accepts? Here's a recipe for a function that tries many different formats until it finds one that works.

Function that supports dividing timedelta by float (Python)

2012-05-17T13:47:07-07:00

Python recipe 578136 by Ben Hoyt (datetime, division, float).

Python 2.x doesn't support dividing a timedelta by a float (only works with int). This function adds support for that.

Convert strings like '5d' and '60s' to timedelta objects (Python)

2011-10-06T14:06:54-07:00

Python recipe 577894 by Dan McDougall (datetime, timedelta).

I wrote this little function for [Gate One](http://vimeo.com/24857127) (a web-based terminal emulator/SSH client)... It converts strings in the format of <num><character> into timedelta objects. It's not rocket science but maybe it'll save someone a few keystrokes :). Besides that, it comes with a really nice Sphinx-ready (reStructuredText) docstring with complete doctests.

Printing current, next, or previous day (Python)

Python recipe 577883 by Andy Barbour (datetime, python, time). Revision 3.

Redate source files using SVN info from $Id:$ (Python)

2010-07-30T10:00:25-07:00

Python recipe 577341 by Michal Niklas (date, datetime, file, files, svn).

Iterates through a directory, reading the data from svn info that looks like:

$Id: svn_redater.py 747 2010-07-30 09:56:08Z mn $

from source files.

Parses the datetime from svn info and if it differs from file modification datetime then changes file datetime

subtract or add a month to a datetime.date or datetime.datetime (Python)

2010-06-25T18:41:19-07:00

Python recipe 577274 by Trent Mick (date, datetime, month).

Adding or subtracting a month to a Python datetime.date or datetime.datetime is a little bit of a pain. Here is the code I use for that. These functions return the same datetime type as given. They preserve time of day data (if that is at all important to you).

Parse HTTP date-time string (Python)

Python recipe 577015 by Sridhar Ratnakumar (datetime, http, parsing).

This recipe will help you parse datetime strings returned by HTTP servers following the RFC 2616 standard (which supports three datetime formats). Credit for this recipe goes to ΤΖΩΤΖΙΟΥ.

Get a posix timestamp from a type 1 uuid (Python)

2008-08-13T18:56:29-07:00

Python recipe 576420 by Kent Tenney (datetime, time, timestamp, uuid).

The uuid timestamp is 60 bits, the number of 100 nanosecond increments since Oct. 15, 1582 This simple function returns a value which makes datetime.datetime.fromtimestamp() happy.

It simply rewinds the code in the standard library's uuid1 function:

nanoseconds = int(time() * 1e9)
# 0x01b21dd213814000 is the number of 100-ns intervals between the
# UUID epoch 1582-10-15 00:00:00 and the Unix epoch 1970-01-01 00:00:00.
timestamp = int(nanoseconds/100) + 0x01b21dd213814000

Convert datetime in python to user friendly representation. (Python)

2009-08-15T01:00:03-07:00

Python recipe 576880 by Jai Vikram Singh Verma (ago, datetime, parse, representation, string, user_friendly).

A small contribution to the developer community.

This module caters to the need of developers who want to put date & time of post in terms like
"X days, Y hrs ago", "A hours B mins ago", etc. in their applications rather then a basic timestamp
like "2009-08-15 03:03:00". Additionally it also
provides since epoch for a given datetime.

It takes in a Python datetime object as an input
and provides a fancy datetime (as I call it) and
the seconds since epoch.

Compare passed day of week to today's day of week (Python)

2009-01-17T20:51:26-08:00

Python recipe 576619 by Samuel Huckins (date, datetime, dayofweek).

This function compares the day of the week of today to the day of the week passed.
