[ncl-talk] unable to convert date and time

[Rick Brownrigg]

I think you want cd_string, not cd_convert:

    http://ncl.ucar.edu/Document/Functions/User_contributed/cd_string.shtml

>From those docs, I'm not sure it will give days as "2nd", "3rd"..."31st",
etc, but it will certain give 2, or 02, etc.

It looks like cd_convert is used to convert various linear time units, ex,
"days from..." to "months from...", etc.
