[ncl-talk] About local time (UTC+9)

[Dave Allured - NOAA Affiliate]

Also I see another problem.  In these two lines which I just sent, make
sure you have ASCII straight double quotes (") in the script before you run
it.  I think I sent you curly double quotes (UTF-8) by mistake.

    time_numeric = cd_inv_string (times, "%Y%N%D%H%M")
    offset_times = cd_string (time_numeric, "%Y%N%D%H%M" )
