Pandas DataFrame and Bokeh TimeSeries


I am trying to use Bokeh together with Pandas. Everything looks good but I cannot display the full date. Bokeh TimeSeries shows only time. Is there any way to solve this ?
Any help would be much appreciated.

print df.index
<class ‘pandas.tseries.index.DatetimeIndex’>
[2015-03-10 11:50:32, …, 2015-03-10 14:32:51]

p = TimeSeries(df, xlabel=‘Time’, ylabel=‘Values]’, width=800, height=400,legend=“top_left”)
