[ncl-talk] Problem with "cd_calendar"

[Alan Brammer]

Mary, 

 A while back I adapted cd_string to work in reverse cd_inv_string.  Pass it a string and the string format and it converts to a cd time.   Would you be interested in including this functionality in future releases?  

I use the function quite a bit and it helps save a ton of time and  lines parsing out the strings and then converting etc. 

Alan.

I want to use it in the format time at units = "minuts since 2014-10-05 06:00:00" with dates = cd_calendar(Time, 0) as specifying in my script (readcsv.ncl). Please, find attached a sample of my data and script.
