title: Get system local timezone in python
body: <p>Seems strange, but I cannot find an easy way to find the local timezone using Pandas/pytz in Python.</p>
  
  <p>I can do:</p>
  
  <pre><code>&gt;&gt;&gt; pd.Timestamp('now', tz='utc').isoformat()
  Out[47]: '2016-01-28T09:36:35.604000+00:00'
  &gt;&gt;&gt; pd.Timestamp('now').isoformat()
  Out[48]: '2016-01-28T10:36:41.830000'
  &gt;&gt;&gt; pd.Timestamp('now').tz_localize('utc') - pd.Timestamp('now', tz='utc')
  Out[49]: Timedelta('0 days 01:00:00')
  </code></pre>
  
  <p>Which will give me the timezone, but this is probably not the best way to do it...
  Is there a command in pytz or pandas to get the system time zone? (preferably in python 2.7 )</p>
