Sue, > Is there a release date for udunits2? It's already out there. See <http://www.unidata.ucar.edu/software/udunits/udunits-2/udunits2.html>. > Could all of this be done with the current udunits? > ( the parsing of the time strings "seconds since 1970-01-01T00:00:00Z" > and recognition as time units?) Yes, the original UDUNITS package will correctly parse the string in question and does have a function for determining whether or not a unit is a temporal one. The original UDUNITS package doesn't support logarithmic units or non-ASCII character encodings.
