Question about units package...

All,

Below is a snippet of of Perl code that uses UDUNITS to translate a date as it
is stored in our netCDF files to something a human can read.

Digging around in the various examples and docs, I have not been able to figure
out how to do the equivalent using the Java units package.  Can somebody please
provide me with a pointer a specific example or tutorial that covers this?

Thanks,
Roland

#!/usr/bin/perl -w

use UDUNITS;

   UDUNITS::init('');

   $time_units = "hours since 1700-1-1";

   if ( !($unit = UDUNITS::scan("$time_units"))) {
      print STDERR "Having trouble finding the units for time.\n";
      print STDERR "$time_units is not a valid time unit.\n";
      die;
   }

   $udtim = 2298168.0;

   $unit->valtocal($udtim, $yr, $mon, $day,
                           $hour, $min, $sec);


   print "The time units are $time_units\n";
   print "The encoded time $udtim is $yr-$mon-$day $hour:$min:$sec\n";
