ERROR: calendar dates must be increasing when running B2000

Dear all,
I would like to run a fully coupled simulation of CESM 2.1.3 for year 2000. As I did not find a "B2000" compset I created a case based on B1850.

I tried to replace "1850" in the long name of B1850 with "2000", and run with the compset with longname "2000_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD". The case is restarted from the restart file in 2000-01-01 (b.e21.BHIST.f19_g17.CMIP6-historical-2deg.001) using hybrid. I made the following settings:
Code:
COMPSET=2000_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD
RES=f19_g17
/data/Atmospheric/CESM-2.1.3/cime/scripts/create_newcase --case $CASENAME --compset $COMPSET --res $RES --compiler gnu --machine fudannhpcc --run-unsupported
./xmlchange RUN_REFCASE=b.e21.BHIST.f19_g17.CMIP6-historical-2deg.001
./xmlchange RUN_REFDATE=2000-01-01
./xmlchange RUN_STARTDATE=0001-01-01
./xmlchange GET_REFCASE=FALSE

However, I got these errors as followed in the run.log:

I further checked the lnd.log, and found the errors when reading fndep_clm_hist_b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensmean_1849-2015_monthly_0.9x1.25_c180926.nc (see Fig below). I checked the fndep_clm_hist_b.e21.BWHIST.f09_g17.CMIP6-historical-WACCM.ensmean_1849-2015_monthly_0.9x1.25_c180926.nc, and found the time axis is not increasing. So, I re-downloaded the file and ran the simulation successfully. I would like to ask if it is reasonable for me to handle it this way? I also attached the lnd.log file for reference.

Look forward to any useful suggestion.

Best regards,
KW
