BUG: Series.plot x-axis labels are off by one year when a timezone is involved
```python
%matplotlib inline

import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

pd.show_versions()

index = np.array([
    '2011-10-01 09:00',
    '2016-10-01 09:00',
], dtype='datetime64[ns]')

values = np.array([
    -0.26,
    -0.01,    
])

data_utc = pd.Series(values, index)
data_utc.index = data_utc.index.tz_localize('UTC')
data_eastern = pd.Series(values, index)
data_eastern.index = data_eastern.index.tz_localize('UTC').tz_convert('US/Eastern')

data_utc.plot(title='UTC')
plt.figure()
data_eastern.plot(title='US/Eastern')
plt.figure()
```
With the Eastern time zone, the x-axis labels are off by a year.

#### Output of ``pd.show_versions()``
