title: Change DateTime input format in django form
body: <p>I am trying to change the DateTime format in one of my django forms.</p>
  
  <p>The format I would like it to accept is:
  day month year hour_minute_seconds timezone
  11 Aug 2015 12:00:00 GMT -> %d %b %Y %H:%M:%S %Z</p>
  
  <p>I have been doing some tests but I have not been able to get the right way.</p>
  
  <p>I have disabled the L10N in the settings.py file so I can use the %b month format.</p>
  
  <p>This is my forms.py file content</p>
  
  <pre><code>from django import forms
  from django.forms import DateTimeField
  
  from web.apps.customer.models import Reported_VPN_User
  
  class Customer_settings_vpn_Form(forms.ModelForm):
  
      event_date = DateTimeField(widget=forms.widgets.DateTimeInput(format="%d %b %Y %H:%M:%S %Z"))
  
      class Meta:
          model = Reported_VPN_User
          fields = '__all__'
  </code></pre>
  
  <p>When I try to input a date in the required format, the form does not allow me to go ahead.</p>
  
  <p>I have been checking the DATETIME_INPUT_FORMAT (<a href="https://docs.djangoproject.com/en/1.8/ref/settings/#std:setting-DATETIME_FORMAT" rel="noreferrer">https://docs.djangoproject.com/en/1.8/ref/settings/#std:setting-DATETIME_FORMAT</a>) and I dont see what I am looking for, but checking the python date documentation (<a href="https://docs.python.org/2/library/datetime.html#strftime-strptime-behavior" rel="noreferrer">https://docs.python.org/2/library/datetime.html#strftime-strptime-behavior</a>) I see that it should be possible.</p>
  
  <p>How can I modify the datetime format so I can make it work as requested?</p>
  
  <p>ps: I am not an expert in django.</p>
