Description of problem:

The version of python-tzlocal in EPEL 7 does not work with systemd, rendering it useless on RHEL 7 or CentOS 7.

This has been fixed in upstream, with version 1.2:

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)

So please update python-tzlocal in EPEL to this version. 

Version-Release number of selected component (if applicable):

1.1.2-4

How reproducible:

Use python-tzlocal on RHEL 7

Steps to Reproduce:
Python 2.7.5 (default, Nov 20 2015, 02:00:19)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from tzlocal import get_localzone
>>> tz = get_localzone()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/site-packages/tzlocal/unix.py", line 108, in get_localzone
    _cache_tz = _get_localzone()
  File "/usr/lib/python2.7/site-packages/tzlocal/unix.py", line 100, in _get_localzone
    return pytz.tzfile.build_tzinfo('local', tzfile)
  File "/usr/lib/python2.7/site-packages/pytz/tzfile.py", line 30, in build_tzinfo
    typecnt, charcnt) =  unpack(head_fmt, fp.read(head_size))
struct.error: unpack requires a string argument of length 44


Actual results:

python throws a stack trace.

Expected results:

As on RHEL 6:
Python 2.6.6 (r266:84292, Jul 22 2015, 16:47:47)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-16)] on linux2
