They have a mix of `Timestamp` and `cftime.DatetimeGregorian` in the time vector which, obviously can not be saved to disk. (I.e. concat worked but not to_netcdf).","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,407864596 https://github.com/pydata/xarray/issues/2754#issuecomment-461830931,https://api.github.com/repos/pydata/xarray/issues/2754,461830931,MDEyOklzc3VlQ29tbWVudDQ2MTgzMDkzMQ==,10194086,2019-02-08T15:02:21Z,2019-02-08T15:02:21Z,MEMBER,"Yes, I meant this warning. Thanks, I understand better now - it makes sense to throw a warning when you unexpectedly get a `cftime` instead of pandas dates. An `option` might be a good way to get consistent datetimes. Especially as the capabilities with `cftime` are progressing. What is still missing once 0.12 is released (plotting and resampling)? I don't have the full overview there. Btw: I am really thrilled to be able to have datetime irrespective of the calendar.
