title: Django timezone.make_aware raised AmbiguousTimeError for 2014-10-26 1:45:00
body: <p>I found some strange things. Here some examples.</p>
  
  <pre><code>from django.utils import timezone
  value = u'2014-10-26 01:45:00'
  #I know that a variable has  'Europe / Moscow' timezone. Let's tell Django about it.
  TZ = timezone.pytz.timezone('Europe/Moscow')
  d = timezone.datetime.strptime(value,'%Y-%m-%d %H:%M:%S')
  print timezone.make_aware(d,TZ)
  #raised AmbiguousTimeError: 2014-10-26 01:45:00
  </code></pre>
  
  <p>And then the fun begins</p>
  
  <pre><code>print timezone.make_aware(d+timezone.timedelta(minutes=15),TZ)
  #out: 2014-10-26 02:00:00+03:00
  print timezone.make_aware(d+timezone.timedelta(minutes=14),TZ)
  #raised AmbiguousTimeError
  print timezone.make_aware(d-timezone.timedelta(minutes=46),TZ)
  #out: 2014-10-26 00:59:00+04:00
  print timezone.make_aware(d-timezone.timedelta(minutes=45),TZ)
  #raised AmbiguousTimeError     
  </code></pre>
  
  <p>So AmbiguousTimeError raised between 2014-10-26 00:59:00 and 2014-10-26 02:00:00</p>
  
  <p>WHY? And how solve it?</p>
