Out[4]: Timestamp('2017-12-31 19:00:00-0500', tz='US/Eastern')
Problem description
The dates in the date_range are not being localized correctly; the dates are being shifted back by the UTC offset, then having the timezone appended to the shifted back date.
Expected Output
I'd expect this to be identical to the equivalent non-linspace behavior call:
