Though I can't speak officially, I believe that the Unidata Program Center
(birthplace of the netCDF package) recommends the use of the UDUNITS
package for the handling of units of time and other physical quantities.
It's freely-available via anonymous FTP:

host: unidata.ucar.edu
file: pub/sdm/udunits.tar.Z.

The User's Guide in the latest netCDF release (version 2.3) also contains a
section on time, units and the UDUNITS package.
