Re: use cd_calendar when it is necessary to read an variable from many directories

Your 'xx' is a standard variable. It is not a 'time' variable as
required by the 'cd_calendar' function:
   http://www.ncl.ucar.edu/Document/Functions/Built-in/cd_calendar.shtml

The documentation states that the 'time' variable

    "Must have a "units" attribute string in the format
    "units since basetime", for example, "days since 1971-1-1"

Hence, your usage
    YMDHMS = cd_calendar(xx, 1)
is not correct.

You should do a printVarSummary(xx)

Is there coordinate information for the named dimensions 'year'
and 'month'? If there is no information, you must create.
