Changes
=======
1.5.1 (2017-12-01)
------------------
- 1.5 had a bug that slipped through testing, fixed that,
increased test coverage.
1.5 (2017-11-30)
----------------
- No longer treats macOS as special, but as a unix.
- get_windows_info.py is renamed to update_windows_mappings.py
- Windows mappings now also contain mappings from deprecated zoneinfo names.
(Preston-Landers, regebro)
1.4 (2017-04-18)
----------------
- I use MIT on my other projects, so relicensing.
1.4b1 (2017-04-14)
------------------
- Dropping support for Python versions nobody uses (2.5, 3.1, 3.2), adding 3.6
Python 3.1 and 3.2 still works, 2.5 has been broken for some time.
- Ayalash's OS X fix didn't work on Python 2.7, fixed that.
1.3.2 (2017-04-12)
------------------
- Ensure closing of subprocess on OS X (ayalash)
DOING: Implementing feedback on the unsubscribe button
DOING: Investigating remaining issues with DOCX export
BLOCKERS: None
- Removed unused imports (jwilk)
- Closes stdout and stderr to get rid of ResourceWarnings (johnwquarles)
- Updated Windows timezones (axil)
1.3 (2016-10-15)
----------------
- #34: Added support for /var/db/zoneinfo
1.2.2 (2016-03-02)
------------------
- #30: Fixed a bug on OS X.
1.2.1 (2016-02-28)
------------------
- Tests failed if TZ was set in the environment. (EdwardBetts)
- Replaces os.popen() with subprocess.Popen() for OS X to
handle when systemsetup doesn't exist. (mckabi, cewing)
1.2 (2015-06-14)
----------------
- Systemd stores no time zone name, forcing us to look at the name of the file
that localtime symlinks to. (cameris)
1.1.2 (2014-10-18)
------------------
- Timezones that has 3 items did not work on Mac OS X.
(Marc Van Olmen)
- Now doesn't fail if the TZ environment variable isn't an Olsen time zone.
- Some timezones on Windows can apparently be empty (perhaps the are deleted).
Now these are ignored.
(Xiaokun Zhu)
1.1.1 (2014-01-29)
------------------
- I forgot to add Etc/UTC as an alias for Etc/GMT.
1.1 (2014-01-28)
----------------
- Adding better support for OS X.
- Added support to map from tzdata/Olsen names to Windows names.
(Thanks to Benjamen Meyer).
1.0 (2013-05-29)
----------------
- Fixed some more cases where spaces needs replacing with underscores.
- Better handling of misconfigured /etc/timezone.
- Better error message on Windows if we can't find a timezone at all.
0.3 (2012-09-13)
----------------
- Windows 7 support.
- Python 2.5 supported; because it only needed a __future__ import.
- Python 3.3 tested, it worked.
- Got rid of relative imports, because I don't actually like them,
so I don't know why I used them in the first place.
- For each Windows zone, use the default zoneinfo zone, not the last one.
0.2 (2012-09-12)
----------------
- Python 3 support.
0.1 (2012-09-11)
----------------
- Initial release.

ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS

THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
HEREUNDER.
The above copyright notice and this permission notice shall be included in
all copies or substantial portions of the Software.
Statement of Purpose
The laws of most jurisdictions throughout the world automatically confer
exclusive Copyright and Related Rights (defined below) upon the creator
and subsequent owner(s) (each and all, an "owner") of an original work of
authorship and/or a database (each, a "Work").
Certain owners wish to permanently relinquish those rights to a Work for
the purpose of contributing to a commons of creative, cultural and
scientific works ("Commons") that the public can reliably and without fear
of later claims of infringement build upon, modify, incorporate in other
works, reuse and redistribute as freely as possible in any form whatsoever
and for any purposes, including without limitation commercial purposes.
These owners may contribute to the Commons to promote the ideal of a free
culture and the further production of creative, cultural and scientific
works, or to gain reputation or greater distribution for their Work in
part through the use and efforts of others.
For these and/or other purposes and motivations, and without any
expectation of additional consideration or compensation, the person
associating CC0 with a Work (the "Affirmer"), to the extent that he or she
is an owner of Copyright and Related Rights in the Work, voluntarily
elects to apply CC0 to the Work and publicly distribute the Work under its
terms, with knowledge of his or her Copyright and Related Rights in the
Work and the meaning and intended legal effect of CC0 on those rights.
1. Copyright and Related Rights. A Work made available under CC0 may be
protected by copyright and related or neighboring rights ("Copyright and
Related Rights"). Copyright and Related Rights include, but are not
limited to, the following:
i. the right to reproduce, adapt, distribute, perform, display,
communicate, and translate a Work;
ii. moral rights retained by the original author(s) and/or performer(s);
iii. publicity and privacy rights pertaining to a person's image or
likeness depicted in a Work;
iv. rights protecting against unfair competition in regards to a Work,
subject to the limitations in paragraph 4(a), below;
v. rights protecting the extraction, dissemination, use and reuse of data
in a Work;
vi. database rights (such as those arising under Directive 96/9/EC of the
European Parliament and of the Council of 11 March 1996 on the legal
protection of databases, and under any national implementation
thereof, including any amended or successor version of such
directive); and
vii. other similar, equivalent or corresponding rights throughout the
world based on applicable law or treaty, and any national
implementations thereof.
2. Waiver. To the greatest extent permitted by, but not in contravention
of, applicable law, Affirmer hereby overtly, fully, permanently,
irrevocably and unconditionally waives, abandons, and surrenders all of
Affirmer's Copyright and Related Rights and associated claims and causes
of action, whether now known or unknown (including existing as well as
future claims and causes of action), in the Work (i) in all territories
worldwide, (ii) for the maximum duration provided by applicable law or
treaty (including future time extensions), (iii) in any current or future
medium and for any number of copies, and (iv) for any purpose whatsoever,
including without limitation commercial, advertising or promotional
purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
member of the public at large and to the detriment of Affirmer's heirs and
successors, fully intending that such Waiver shall not be subject to
revocation, rescission, cancellation, termination, or any other legal or
equitable action to disrupt the quiet enjoyment of the Work by the public
as contemplated by Affirmer's express Statement of Purpose.
3. Public License Fallback. Should any part of the Waiver for any reason
be judged legally invalid or ineffective under applicable law, then the
Waiver shall be preserved to the maximum extent permitted taking into
account Affirmer's express Statement of Purpose. In addition, to the
extent the Waiver is so judged Affirmer hereby grants to each affected
person a royalty-free, non transferable, non sublicensable, non exclusive,
irrevocable and unconditional license to exercise Affirmer's Copyright and
Related Rights in the Work (i) in all territories worldwide, (ii) for the
maximum duration provided by applicable law or treaty (including future
time extensions), (iii) in any current or future medium and for any number
of copies, and (iv) for any purpose whatsoever, including without
limitation commercial, advertising or promotional purposes (the
"License"). The License shall be deemed effective as of the date CC0 was
applied by Affirmer to the Work. Should any part of the License for any
reason be judged legally invalid or ineffective under applicable law, such
partial invalidity or ineffectiveness shall not invalidate the remainder
of the License, and in such case Affirmer hereby affirms that he or she
will not (i) exercise any of his or her remaining Copyright and Related
Rights in the Work or (ii) assert any associated claims and causes of
action with respect to the Work, in either case contrary to Affirmer's
express Statement of Purpose.
4. Limitations and Disclaimers.
a. No trademark or patent rights held by Affirmer are waived, abandoned,
surrendered, licensed or otherwise affected by this document.
b. Affirmer offers the Work as-is and makes no representations or
warranties of any kind concerning the Work, express, implied,
statutory or otherwise, including without limitation warranties of
title, merchantability, fitness for a particular purpose, non
infringement, or the absence of latent or other defects, accuracy, or
the present or absence of errors, whether or not discoverable, all to
the greatest extent permissible under applicable law.
c. Affirmer disclaims responsibility for clearing rights of other persons
that may apply to the Work or any use thereof, including without
limitation any person's Copyright and Related Rights in the Work.
Further, Affirmer disclaims responsibility for obtaining any necessary
consents, permissions or other rights required for any use of the
Work.
d. Affirmer understands and acknowledges that Creative Commons is not a
party to this document and has no duty or obligation with respect to
this CC0 or use of the Work.
THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR
IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY,

AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER

tzlocal
=======
This Python module returns a `tzinfo` object with the local timezone information under Unix and Win-32.
It requires `pytz`, and returns `pytz` `tzinfo` objects.
This module attempts to fix a glaring hole in `pytz`, that there is no way to
get the local timezone information, unless you know the zoneinfo name, and
under several Linux distros that's hard or impossible to figure out.
Also, with Windows different timezone system using pytz isn't of much use
unless you separately configure the zoneinfo timezone name.
With `tzlocal` you only need to call `get_localzone()` and you will get a
`tzinfo` object with the local time zone info. On some Unices you will still
not get to know what the timezone name is, but you don't need that when you
have the tzinfo file. However, if the timezone name is readily available it
will be used.
Supported systems
-----------------
These are the systems that are in theory supported:
* Windows 2000 and later
* Any unix-like system with a /etc/localtime or /usr/local/etc/localtime
If you have one of the above systems and it does not work, it's a bug.
Please report it.
Usage
-----
Load the local timezone:
>>> from tzlocal import get_localzone
>>> tz = get_localzone()
>>> tz
<DstTzInfo 'Europe/Warsaw' WMT+1:24:00 STD>
Create a local datetime:
>>> from datetime import datetime
>>> dt = tz.localize(datetime.now())
>>> dt
datetime.datetime(2012, 9, 11, 14, 43, 42, 518871, tzinfo=<DstTzInfo 'Europe/Warsaw' CEST+2:00:00 DST>)
Lookup another timezone with `pytz`:
>>> import pytz
>>> eastern = pytz.timezone('US/Eastern')
Convert the datetime:
>>> dt.astimezone(eastern)
datetime.datetime(2012, 9, 11, 8, 43, 42, 518871, tzinfo=<DstTzInfo 'US/Eastern' EDT-1 day, 20:00:00 DST>)
