ValueError: Cannot compare tz-naive and tz-aware timestamps

[kontinuity]

Trying to generate a time series based on timezone raises exception.

>>> import pandas
>>> pandas.date_range('2013-01-01T00:00:00+05:30','2014-03-07T23:59:59+05:30',freq='AS')

create this way

In [3]: pandas.date_range('2013-01-01T00:00:00','2014-03-07T23:59:59',freq='AS','US/Eastern')
Out[3]: 
<class 'pandas.tseries.index.DatetimeIndex'>
[2013-01-01 00:00:00, 2014-01-01 00:00:00]
Length: 2, Freq: AS-JAN, Timezone: US/Eastern

What you initially are suggesting requires a modification, want to do a pull-request for this?

Can work on current master, maybe fixed in #7465. Will add test cases for this.

pd.date_range('2013-01-01T00:00:00+05:30','2014-03-07T23:59:59+05:30',freq='AS')
# <class 'pandas.tseries.index.DatetimeIndex'>
# [2013-01-01 00:00:00+05:30, 2014-01-01 00:00:00+05:30]
