Warning message for time series plots?

Hi community,

(I’ll post a reproducible example in a bit…)

I’m displaying a time-series hv.Curve with Holoviews, and I’m getting the following warning printed:

/lib/python3.6/site-packages/holoviews/core/data/__init__.py:514: UserWarning:
Discarding nonzero nanoseconds in conversion

which appear to have originated from Pandas.

This seems harmless but annoying. Do we know what caused this message to be printed?
