[ncl-talk] Strange units of time

[Rick Brownrigg]

Hi,

Its hard to say where the issue lies, offhand. Do you have other tools that
can look at that HDF5 file, and is the odd units string absent there?

If so, what version of NCL are you using?  If you are using the latest,
6.4.0, are you able to send that HDF5 file to me? (either email directly,
is not too large, or see the instructions about our FTP site:

   http://ncl.ucar.edu/ftp_files.shtml

)

Rick
