I have a pandas Series with values of type datetime64[ns]. The dates are in EST timezone, and I would like to convert them to UTC timezone.

E.g.,

 s=pd.Series(pd.date_range('2012-1-1 1:30',periods=3,freq='min'))

How to convert s to UTC?

(Note that I don't actually use date_range() so using its tz parameter is not an option.)
