Hi Mr. Brammer,
Thank you for this script. The only issue that I am facing with it is when
I use "print(cd_calendar(date,0))", it's just printing the same date which
is 2014-10-05 06:00:00. The date is no varying.
load "cd_inv_string.ncl"
time = "10/05/2014 06:00:00"
time_format = "%N/%D/%Y %H:%M:%S"
time_format at units = "minutes since 2014-10-05 06:00:00”
date = cd_inv_string(time, time_format)
print(cd_calendar(date,0))
What's wrong with my script?
Best regards
