Userwarning non-nanosecond datetime

[kingkong-cmd]

Hi Matthew,

I keep getting these warnings when reading grib wind data files from NOAA. Logs says it's coming from gribberish, but is it actually coming from xarray?

Not a life ending problem, but it is flooding my logs to the point where they become unreadable. Using newest version of xarray/gribberish, but was same before. Can't really convert to "nanosecond precision" since files are from NOAA.

.venv/lib/python3.13/site-packages/gribberish/gribberish_backend.py:50: UserWarning: Converting non-nanosecond precision datetime values to nanosecond precision. This behavior can eventually be relaxed in xarray, as it is an artifact from pandas which is now beginning to support non-nanosecond precision values. This warning is caused by passing non-nanosecond np.datetime64 or np.timedelta64 values to the DataArray or Variable constructor; it can be silenced by converting the values to nanosecond precision ahead of time.
