BUG: fillna() for tz-aware timestamps causes an exception (original) (raw)

Suppose I have a DataFrame of timestamps:

df = pd.DataFrame({'A': [pd.Timestamp('2012-11-11 00:00:00'), pd.Timestamp('2012-11-11 00:00:00')]})

I can attempt to fill any nulls:

In [23]: df.fillna(method='pad') Out[23]: A 0 2012-11-11 1 2012-11-11

Now suppose my timestsamps are tz-aware:

df = pd.DataFrame({'A': [pd.Timestamp('2012-11-11 00:00:00+00:00'), pd.Timestamp('2012-11-11 00:00:00+00:00')]})

This causes an error:

In [25]: df.fillna(method='pad') ... ValueError: total size of new array must be unchanged

This does not appear to be fixed by #14960.
