tzinfo object for the local timezone
Project description
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>)

Changes
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.
