Series.
tshift
(self, periods=1, freq=None, axis=0)[source]¶ Shift the time index, using the index’s frequency if available.
Parameters: - periods : int
Number of periods to move, can be positive or negative
- freq : DateOffset, timedelta, or time rule string, default None
Increment to use from the tseries module or time rule (e.g. ‘EOM’)
- axis : int or basestring

Returns: - shifted : Series/DataFrame
Notes
If freq is not specified then tries to use the freq or inferred_freq attributes of the index. If neither of those attributes exist, a ValueError is thrown
