Problem description

Given the original time dimension: python ds = xr.open_mfdataset("C:\\Users\\janis\\.cate\\data_stores\\local\\local.SST_should_fail\\*.nc", decode_cf=False) <xarray.DataArray 'time' (time: 32)> array([788961600, 789048000, 789134400, 789220800, 789307200, 789393600, 789480000, 789566400, 789652800, 789739200, 789825600, 789912000, 789998400, 790084800, 790171200, 790257600, 790344000, 790430400, 790516800, 790603200, 790689600, 790776000, 790862400, 790948800, 791035200, 791121600, 791208000, 791294400, 791380800, 791467200, 791553600, 791640000], dtype=int64) Coordinates: * time (time) int64 788961600 789048000 789134400 789220800 789307200 ...

Expected Output

With xarray == 0.10.0 the output is as expected: python ds = xr.open_mfdataset("C:\\Users\\janis\\.cate\\data_stores\\local\\local.SST_should_fail\\*.nc", decode_cf=True) <xarray.DataArray 'time' (time: 32)> array(['2006-01-01T12:00:00.000000000', '2006-01-02T12:00:00.000000000', '2006-01-03T12:00:00.000000000', '2006-01-04T12:00:00.000000000', '2006-01-05T12:00:00.000000000', '2006-01-06T12:00:00.000000000', '2006-01-07T12:00:00.000000000', '2006-01-08T12:00:00.000000000', '2006-01-09T12:00:00.000000000', '2006-01-10T12:00:00.000000000', '2006-01-11T12:00:00.000000000', '2006-01-12T12:00:00.000000000', '2006-01-13T12:00:00.000000000', '2006-01-14T12:00:00.000000000', '2006-01-15T12:00:00.000000000', '2006-01-16T12:00:00.000000000', '2006-01-17T12:00:00.000000000', '2006-01-18T12:00:00.000000000', '2006-01-19T12:00:00.000000000', '2006-01-20T12:00:00.000000000', '2006-01-21T12:00:00.000000000', '2006-01-22T12:00:00.000000000', '2006-01-23T12:00:00.000000000', '2006-01-24T12:00:00.000000000', '2006-01-25T12:00:00.000000000', '2006-01-26T12:00:00.000000000', '2006-01-27T12:00:00.000000000', '2006-01-28T12:00:00.000000000', '2006-01-29T12:00:00.000000000', '2006-01-30T12:00:00.000000000', '2006-01-31T12:00:00.000000000', '2006-02-01T12:00:00.000000000'], dtype='datetime64[ns]') Coordinates: * time (time) datetime64[ns] 2006-01-01T12:00:00 2006-01-02T12:00:00 ...
