Thanks @arfriedman . Here's how to solve it

``` python import pandas as pd

air["time"] = air.time + pd.Timedelta("1D") ```

Today shift operates in "index space" i.e. it ignores any coordinate labels and simply moves values along an axis by integer offsets. This is conceptually different to your proposal for supporting a frequency string. I can see it being useful though.

The addition above is what you would do to shift longitude values by 0.5 for example. Perhaps that would be a useful API addition as shift_labels?

Let's see what others think.
