Dataset problem: UKESM1-0-LL missing years in Tasmin and Tasmax r14i1p1f1

[Karen-A-Garcia]

After looking at the metadata for UKESM1-0-LL r14i1p1f1 from NIMS-KMA for both tasmin and tasmax in CMIP historical, seems to be that there is a time jump from Dec 30, 1927 to Jan 1, 1946. This brings up the CMORCheckError message:

esmvalcore.cmor.check.CMORCheckError: There were errors in variable tasmin:
 time: Frequency day does not match input data
in cube:
air_temperature / (K)               (time: 29520; latitude: 144; longitude: 192)
    Dimension coordinates:

There should 36000 values time values for the amount of time and frequency that is described by the file name and if you look at the time between 28078 and 28082 index of the you'll see the time discrepancy.

with xr.open_dataset(file_error_tasmin) as ds:
    ds = ds.isel(lat=143, lon=191)
    display(ds.time.values[28078:28082])

array([cftime.Datetime360Day(1927, 12, 29, 12, 0, 0, 0, has_year_zero=True),
       cftime.Datetime360Day(1927, 12, 30, 12, 0, 0, 0, has_year_zero=True),
       cftime.Datetime360Day(1946, 1, 1, 12, 0, 0, 0, has_year_zero=True),
       cftime.Datetime360Day(1946, 1, 2, 12, 0, 0, 0, has_year_zero=True)],
      dtype=object)

I write this issue purely to bring awareness to this as I will not be trying to write a fix for this.
