An important point to note while giving a historical run

The range of dates in run_timestamp should be such that it lies within the time series of the input files.

Meaning of this error

FATAL: From function set_date_i:Invalid date. Date=1850-02-00 00:00:00

There is a file in  the input going to the model which is not having a day stamp, i.e. it might be having the stamp like 185002 rather than 18500215 or 185002.5


Fixing the time dimension

# 1. extract time from the file to create a new file with only time:
 ncks -v time

# 2. remove the time variable from (which removes the problematic `serial_date_number dimension`)
 ncks -C -x -v time

#3. Fix the file manually, with a text editor:
 ncdump > time.txt   # dump netCDF to text
    ## text-edit time.txt to fix up header, 
    ## creating time = UNLIMITED ; // (12053 currently)
 ncgen -o < time.txt   # remake netCDF from text

# 4. Finally, concatenate the new time variable file into
 ncks -A
