What is your issue?

Recently, I have been working with some netCDF data that has a time dimension in the format of years since 850-01-01 0:0:0. However, I encountered some issues when using xarray to read in and analyze the data. Specifically, I found that xarray is not able to parse this time format directly, and I also tried using other libraries like netcdf4 and cftime, but to no avail.

ValueError: In general, units must be one of 'microseconds', 'milliseconds', 'seconds', 'minutes', 'hours', or 'days' (or select abbreviated versions of these). For the '360_day' calendar, 'months' can also be used, or for the 'noleap' calendar 'common_years' can also be used. Got 'years' instead, which are not recognized.

I understand that xarray has been designed to handle various types of time formats, but I have not been able to find a solution for this particular format. Thank you very much for your time and consideration.
