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')
|
|
|
|
|
|
Development
|
|
-----------
|
|
|
|
For ease of development, there is a Makefile that will help you with basic tasks,
|
|
like creating a development environment with all the necessary tools (although
|
|
you need a supported Python version installed first)::
|
|
|
|
$ make devenv
|
|
|
|
To run tests::
|
|
|
|
$ make test
|
|
|
|
Check the syntax::
|
|
|
|
$ make check
|
