Good!

The "print" statement should be after the call to "udparse" because that
routine sets the values of the "iyear", "imonth", "iday", and "ihour"
variables.

What are the types of the following variables: xtime, iyear, imonth,
iday, ihour?

What is the type of the netCDF variable corresponding to "itimeid"?

What is the "udparse" routine?  The routine in the UDUNITS package that
converts DOUBPELPRECISION values to calendar and clock time is
"utCalendar".
