+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.
+
+Please note that if you getting a time zone called ``local``, this is not a bug, it's
+actually the main feature of ``tzlocal``, that even if your system does NOT have a configuration file
+with the zoneinfo name of your time zone, it will still work.
+
+You can also use ``tzlocal`` to get the name of your local timezone, but only if your system is
+configured to make that possible. ``tzlocal`` looks for the timezone name in ``/etc/timezone``, ``/var/db/zoneinfo``,
+``/etc/sysconfig/clock`` and ``/etc/conf.d/clock``. If your ``/etc/localtime`` is a symlink it can also extract the
+name from that symlink.
+
+If you need the name of your local time zone, then please make sure your system is properly configured to allow that.
+If it isn't configured, tzlocal will default to UTC.
+
+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(2015, 4, 10, 7, 22))
+    >>> dt
+    datetime.datetime(2015, 4, 10, 7, 22, 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(2015, 4, 10, 1, 22, tzinfo=<DstTzInfo 'US/Eastern' EDT-1 day, 20:00:00 DST>)

+Changes
+=======
+
+2.1 (2020-05-08)
+----------------
+
+- No changes.
+
+
+2.1b1 (2020-02-08)
+------------------
+
+- The is_dst flag is wrong for Europe/Dublin on some Unix releases.
+  I changed to another way of determining if DST is in effect or not.
+
+- Added support for Python 3.7 and 3.8. Dropped 3.5 although it still works.
+
+
+2.0.0 (2019-07-23)
+------------------
+
+- No differences since 2.0.0b3
+
+Major differences since 1.5.1
+.............................
+
+- When no time zone configuration can be find, tzlocal now return UTC.
+  This is a major difference from 1.x, where an exception would be raised.
+  This change is because Docker images often have no configuration at all,
+  and the unix utilities will then default to UTC, so we follow that.
+
+- If tzlocal on Unix finds a timezone name in a /etc config file, then
+  tzlocal now verifies that the timezone it fouds has the same offset as
+  the local computer is configured with. If it doesn't, something is
+  configured incorrectly. (Victor Torres, regebro)
+
+- Get timezone via Termux `getprop` wrapper on Android. It's not officially
+  supported because we can't test it, but at least we make an effort.
+  (Jean Jordaan)
+
+Minor differences and bug fixes
+...............................
+
+- Skip comment lines when parsing /etc/timezone. (Edward Betts)
+
+- Don't load timezone from current directory. (Gabriel Corona)
+
+- Now verifies that the config files actually contain something before
+  reading them. (Zackary Welch, regebro)
+
+- Got rid of a BytesWarning (Mickaël Schoentgen)
+
+- Now handles if config file paths exists, but are directories.
+
+- Moved tests out from distributions
+
+- Support wheels
+
+
+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)
+
+- 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.

+tzlocal
+=======
+
+API CHANGE!
+-----------
+
+With version 3.0 of tzlocal, tzlocal no longer returned `pytz` objects, but
+`zoneinfo` objects, which has a different API. Since 4.0, it now restored
+partial compatibility for `pytz` users through Paul Ganssle's
+`pytz_deprecation_shim`.
+
+tzlocal 4.0 also adds an official function `get_localzone_name()` to get only
+the timezone name, instead of a timezone object. On unix, it can raise an
+error if you don't have a timezone name configured, where `get_localzone()`
+will succeed, so only use that if you need the timezone name.
+
+4.0 also adds way more information on what is going wrong in your
+configuration when the configuration files are unclear or contradictory.
+
+Version 5.0 removes the `pytz_deprecation_shim`, and now only returns
+`zoneinfo` objects, like verion 3.0 did. If you need `pytz` objects, you have
+to stay on version 4.0. If there are bugs in version 4.0, I will release
+updates, but there will be no further functional changes on the 4.x branch.
+
+
+Info
+----
+
+This Python module returns the `IANA time zone name
+<https://www.iana.org/time-zones>`_ for your local time zone or a ``tzinfo``
+object with the local timezone information, under Unix and Windows.
+
+It requires Python 3.8 or later, and will use the ``backports.tzinfo``
+package, for Python 3.8.
+
+This module attempts to fix a glaring hole in the ``pytz`` and ``zoneinfo``
+modules, 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.
+
+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.
+
+What it's not for
+-----------------
+
+It's not for converting the current time between UTC and your local time. There are
+other, simpler ways of doing this. This is ig you need to know things like the name
+of the time zone, or if you need to be able to convert between your time zone and
+another time zone for times that are in the future or in the past.
+
+For current time conversions to and from UTC, look in the Python ``time`` module.
+
+
+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.
+
+Please note that if you are getting a time zone called ``local``, this is not
+a bug, it's actually the main feature of ``tzlocal``, that even if your
+system does NOT have a configuration file with the zoneinfo name of your time
+zone, it will still work.
+
+You can also use ``tzlocal`` to get the name of your local timezone, but only
+if your system is configured to make that possible. ``tzlocal`` looks for the
+timezone name in ``/etc/timezone``, ``/var/db/zoneinfo``,
+``/etc/sysconfig/clock`` and ``/etc/conf.d/clock``. If your
+``/etc/localtime`` is a symlink it can also extract the name from that
+symlink.
+
+If you need the name of your local time zone, then please make sure your
+system is properly configured to allow that.
+
+If your unix system doesn't have a timezone configured, tzlocal will default
+to UTC.
+
+Notes on Docker
+---------------
+
+It turns out that Docker images frequently have broken timezone setups.
+This usually resuts in a warning that the configuration is wrong, or that
+the timezone offset doesn't match the found timezone.
+
+The easiest way to fix that is to set a TZ variable in your docker setup
+to whatever timezone you want, which is usually the timezone your host
+computer has.
+
+Usage
+-----
+
+Load the local timezone:
+
+    >>> from tzlocal import get_localzone
+    >>> tz = get_localzone()
+    >>> tz
+    zoneinfo.ZoneInfo(key='Europe/Warsaw')
+
+Create a local datetime:
+
+    >>> from datetime import datetime
+    >>> dt = datetime(2015, 4, 10, 7, 22, tzinfo=tz)
+    >>> dt
+    datetime.datetime(2015, 4, 10, 7, 22, tzinfo=zoneinfo.ZoneInfo(key='Europe/Warsaw'))
+
+Lookup another timezone with ``zoneinfo`` (``backports.zoneinfo`` on Python 3.8 or earlier):
+
+    >>> from zoneinfo import ZoneInfo
+    >>> eastern = ZoneInfo('US/Eastern')
+
+Convert the datetime:
+
+    >>> dt.astimezone(eastern)
+    datetime.datetime(2015, 4, 10, 1, 22, tzinfo=zoneinfo.ZoneInfo(key='US/Eastern'))
+
+If you just want the name of the local timezone, use `get_localzone_name()`:
+
+    >>> from tzlocal import get_localzone_name
+    >>> get_localzone_name()
+    "Europe/Warsaw"
+
+Please note that under Unix, `get_localzone_name()` may fail if there is no zone
+configured, where `get_localzone()` would generally succeed.
+
+Troubleshooting
+---------------
+
+If you don't get the result you expect, try running it with debugging turned on.
+Start a python interpreter that has tzlocal installed, and run the following code::
+
+    import logging
+    logging.basicConfig(level="DEBUG")
+    import tzlocal
+    tzlocal.get_localzone()
+
+The output should look something like this, and this will tell you what
+configurations were found::
+
+    DEBUG:root:/etc/timezone found, contents:
+     Europe/Warsaw
+
+    DEBUG:root:/etc/localtime found

+tzlocal
+=======
+
+API CHANGE!
+-----------
+
+With version 3.0 of tzlocal, tzlocal no longer returned `pytz` objects, but
+`zoneinfo` objects, which has a different API. Since 4.0, it now restored
+partial compatibility for `pytz` users through Paul Ganssle's
+`pytz_deprecation_shim`.
+
+tzlocal 4.0 also adds an official function `get_localzone_name()` to get only
+the timezone name, instead of a timezone object. On unix, it can raise an
+error if you don't have a timezone name configured, where `get_localzone()`
+will succeed, so only use that if you need the timezone name.
+
+4.0 also adds way more information on what is going wrong in your
+configuration when the configuration files are unclear or contradictory.
+
+Version 5.0 removes the `pytz_deprecation_shim`, and now only returns
+`zoneinfo` objects, like verion 3.0 did. If you need `pytz` objects, you have
+to stay on version 4.0. If there are bugs in version 4.0, I will release
+updates, but there will be no further functional changes on the 4.x branch.
+
+
+Info
+----
+
+This Python module returns the `IANA time zone name
+<https://www.iana.org/time-zones>`_ for your local time zone or a ``tzinfo``
+object with the local timezone information, under Unix and Windows.
+
+It requires Python 3.8 or later, and will use the ``backports.tzinfo``
+package, for Python 3.8.
+
+This module attempts to fix a glaring hole in the ``pytz`` and ``zoneinfo``
+modules, 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.
+
+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.
+
+What it's not for
+-----------------
+
+It's not for converting the current time between UTC and your local time. There are
+other, simpler ways of doing this. This is ig you need to know things like the name
+of the time zone, or if you need to be able to convert between your time zone and
+another time zone for times that are in the future or in the past.
+
+For current time conversions to and from UTC, look in the Python ``time`` module.
+
+
+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.
+
+Please note that if you are getting a time zone called ``local``, this is not
+a bug, it's actually the main feature of ``tzlocal``, that even if your
+system does NOT have a configuration file with the zoneinfo name of your time
+zone, it will still work.
+
+You can also use ``tzlocal`` to get the name of your local timezone, but only
+if your system is configured to make that possible. ``tzlocal`` looks for the
+timezone name in ``/etc/timezone``, ``/var/db/zoneinfo``,
+``/etc/sysconfig/clock`` and ``/etc/conf.d/clock``. If your
+``/etc/localtime`` is a symlink it can also extract the name from that
+symlink.
+
+If you need the name of your local time zone, then please make sure your
+system is properly configured to allow that.
+
+If your unix system doesn't have a timezone configured, tzlocal will default
+to UTC.
+
+Notes on Docker
+---------------
+
+It turns out that Docker images frequently have broken timezone setups.
+This usually resuts in a warning that the configuration is wrong, or that
+the timezone offset doesn't match the found timezone.
+
+The easiest way to fix that is to set a TZ variable in your docker setup
+to whatever timezone you want, which is usually the timezone your host
+computer has.
+
+Usage
+-----
+
+Load the local timezone:
+
+    >>> from tzlocal import get_localzone
+    >>> tz = get_localzone()
+    >>> tz
+    zoneinfo.ZoneInfo(key='Europe/Warsaw')
+
+Create a local datetime:
+
+    >>> from datetime import datetime
+    >>> dt = datetime(2015, 4, 10, 7, 22, tzinfo=tz)
+    >>> dt
+    datetime.datetime(2015, 4, 10, 7, 22, tzinfo=zoneinfo.ZoneInfo(key='Europe/Warsaw'))
+
+Lookup another timezone with ``zoneinfo`` (``backports.zoneinfo`` on Python 3.8 or earlier):
+
+    >>> from zoneinfo import ZoneInfo
+    >>> eastern = ZoneInfo('US/Eastern')
+
+Convert the datetime:
+
+    >>> dt.astimezone(eastern)
+    datetime.datetime(2015, 4, 10, 1, 22, tzinfo=zoneinfo.ZoneInfo(key='US/Eastern'))
+
+If you just want the name of the local timezone, use `get_localzone_name()`:
+
+    >>> from tzlocal import get_localzone_name
+    >>> get_localzone_name()
+    "Europe/Warsaw"
+
+Please note that under Unix, `get_localzone_name()` may fail if there is no zone
+configured, where `get_localzone()` would generally succeed.
+
+Troubleshooting
+---------------
+
+If you don't get the result you expect, try running it with debugging turned on.
+Start a python interpreter that has tzlocal installed, and run the following code::
+
+    import logging
+    logging.basicConfig(level="DEBUG")
+    import tzlocal
+    tzlocal.get_localzone()
+
+The output should look something like this, and this will tell you what
+configurations were found::
+
+    DEBUG:root:/etc/timezone found, contents:
+     Europe/Warsaw
+
+    DEBUG:root:/etc/localtime found
+    DEBUG:root:2 found:
+     {'/etc/timezone': 'Europe/Warsaw', '/etc/localtime is a symlink to': 'Europe/Warsaw'}
+    zoneinfo.ZoneInfo(key='Europe/Warsaw')
