[ncl-talk] unable to convert date and time

[Dennis Shea]

No function .... just straight forward programming. You can create a
function if you want.

 month = (/"jan","feb","mar","apr","may","jun" \
          ,"jul","aug","sep","oct","nov","dec"/)

 yyyymmdd = 20090402

 yyyy    = yyyymmdd/10000
 mmdd = yyyymmdd-(yyyy*10000)
 mm     = mmdd/100
 dd       = mmdd-(mm*100)
 print("yyyy="+yyyy+": mm="+mm+": dd="+dd)

 DATE = sprinti("%0.2i", mm) + month(mm-1) + yyyy
 print(DATE)
