Description of problem:
The application 'redhat-config-date' doesn't write or read the imezone from the
/etc/sysconfig/date nor /etc/localtime file. It results in a program's fatal
exception, (in innermost last) saying that the currentEntry of type NoneType
doesn't have a property 'tz': 

Traceback (most recent call last):
  File "./redhat-config-date.py", line 35, in ?
    mainWindow.mainWindow().stand_alone()
  File "./mainWindow.py", line 181, in __init__
    self.timezonePage = timezone_gui.timezonePage()
  File "./timezone_gui.py", line 50, in __init__
    self.tz = TimezoneMap(zonetab, self.default, map=path)
  File "./timezone_map_gui.py", line 139, in __init__
    self.setCurrent(self.currentEntry)
  File "./timezone_map_gui.py", line 180, in setCurrent
    self.markers[self.currentEntry.tz].hide()
AttributeError: 'NoneType' object has no attribute 'tz'

Adding  entry = self.currentEntry under the 'if not entry' statement in the
TimezoneMap.setCurrent() function (under the line #176 of the
timezone_map_gui.py file) makes the application run without an exception, but
does not solve the main problem. In general, this bug makes the
redhat-config-date application unusable. This is why the priority is set to 'high'.

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


How reproducible:
Always

Steps to Reproduce:
1. Run it first time, set the time zone to something like "Europe/London"
2. Second time it won't run, crashing with a fatal exception.
	

Actual Results:  Traceback (most recent call last):
  File "./redhat-config-date.py", line 35, in ?
    mainWindow.mainWindow().stand_alone()
  File "./mainWindow.py", line 181, in __init__
    self.timezonePage = timezone_gui.timezonePage()
  File "./timezone_gui.py", line 50, in __init__
    self.tz = TimezoneMap(zonetab, self.default, map=path)
  File "./timezone_map_gui.py", line 139, in __init__
    self.setCurrent(self.currentEntry)
  File "./timezone_map_gui.py", line 180, in setCurrent
    self.markers[self.currentEntry.tz].hide()
AttributeError: 'NoneType' object has no attribute 'tz'


Expected Results:  I expected it to show a dialog. When this program is fixed
with a noted  'entry = self.currentEntry' line under the 'if not entry:'
statement in the TimezoneMap.setCurrent() function (under the line #176 of the
timezone_map_gui.py file), the program runs succesfully, but lacks to correctly
determine the curent timezone (even if it was set before using it). It always
falls back to the New York timezone.
