[ncl-talk] Problem with "cd_calendar"

[Amadou Coulibaly]

Hi Mary,

After persing into my time array, I got year, month, day, hour, minute. But
what about second since it is not appearing in my timestamp, which is in
format mm/dd/yyyy hh:MM? And how to write time at units since my timestamp
starts on 10/05/2014 06:00:00? And after persing my time I converted year,
day, month, hour, minute into interger as:

  month   = str_get_field(time,1,"/")
  day     = str_get_field(time,2,"/")
  year    = str_get_field(time,3,"/ ")
  hour    = str_get_field(time,2," :")
  minute  = str_get_field(time,3," :")
  second  = str_get_field(time,3," :") ????????

  yyyy = stringtointeger(year)
  mm   = stringtointeger(month)
  dd   = stringtointeger(day)
  hh   = stringtointeger(hour)
  MM   = stringtointeger(minute)
  ss   = stringtointeger(second)???????

  time at units = "hour since 2014-10-05 06:00:00" ????????

  date = cd_inv_calendar(yyyy, mm, dd, hh, MM, ss, time at units, 0)

After this, my variable "date" is just printing out missing values. What's
wrong with that?

Best regards
